About Gamma
Written by the company
Gamma is a leading provider of Unified Communications as a Service (UCaaS) into the UK, Dutch, Spanish and German business markets, supplying communication solutions directly and via our extensive network of trusted channel partners.
Of course, sometimes customers may need to reach out due to any issues they may have experienced - we encourage customers to contact us to resolve these issues promptly. Please click the link at the bottom to raise a general complaint about our products or services, and we will be happy to look into it.
Regarding scams and nuisance calls, we are Ofcom registered, fully compliant with regulations and we take the misuse of our numbers very seriously. Gamma is a business-to-business (B2B) wholesaler for number ranges to thousands of businesses across Europe. Therefore, it can appear that Gamma is making calls to the general public or able to control who uses them - this is not the case. Our numbers are being, at times, misused by other businesses, or non-Gamma numbers are ‘spoofed’ to make it appear as though Gamma is calling when this is not the case.
With that being said, we want to help clamp down on nuisance calls in any way we can. Therefore, we would be happy to investigate any reports to check the current owner of the numbers and can act where applicable if they are ours. Instead of leaving reviews, we would kindly ask that you provide the details of the numbers that have called you, including timestamps with our Misuse team. It helps to provide the number that received the call so we would ask that you complete the form via the link at the bottom. Our Misuse and Fraud teams can then investigate the situation.
However, if you do not want to contact us further, we would suggest reporting the numbers to the police, via www.actionfraud.police.uk or call 0300 123 2040 (if in England, Wales or Northern Ireland). If in Scotland, report to Police Scotland by calling 101.

Gamma - Migrations made easy
Migrating numbers between clients and products can sometimes be cumbersome and/or complicated but with the Gamma portal, this process has been made easy and depending on what is being migrated, it is automated, without having to speak to anyone. Very efficient and prompt service

The staff at Gamma are fantastic, you just can't fault them. I genuinely look forward to calling in. There a multitude of telecoms suppliers in the market but if you want a dedicated, helpful team that you can rely on then I'd thoroughly recommend Gamma! Always easy to work with.

Another person subject to Indian caller purporting to be from Virgin/O2 using your number / 02039597785
I have blocked them. Sorry your company is being subject to these scammers.

Do NOT trust this company
Having been a customer for many years, we cancelled at the start of this year. This company continued to take direct debits, without authority.
After we cancelled the DD the credit control team started chasing us, despite agreeing they owed us money.
Getting a refund is proving nigh on impossible, with them constantly requesting our bank details, amd the latest ruse being to ignore a company name change and insisting we have an account in the old company name, which would be illegal.
They were happy to take our money but don't want to return what they have basically stolen from us.
Avoid this company - absolutely not to be trusted.

Gamma Group Website: A Frustrating User Journey Through Outdated Design and Poor Navigation
Gamma Group's website fails to impress from the moment you land on its homepage. The design feels like a relic from a bygone era, with a cluttered layout and a color scheme that lacks vibrancy and modern appeal. Navigation is particularly problematic, with confusing menus and a lack of clear organization that makes finding specific information a daunting task.
