I’ve been trying to talk to them since…

I’ve been trying to talk to them since 1 week but all attempts bring me to a AI assistant who is useless. I have issues with hitting consumption being 200% higher than normal since a new neighbor moved to my building floor. There’s clearly something wrong but I can’t reach out to ISTA by any chance ! I’m already in contact with my lawyer about it.

Hello, I understand your frustration. For any questions regarding your heating cost statement, please contact your landlord or property management first. They are always the initial point of contact for tenants and will involve us if further clarification is needed. Together, we will find a solution then. Kind regards - Liam from the ista Team

Ista's employee installed the meter for…

Ista's employee installed the meter for our heating system wrongly and this caused significant increase in our yearly bill. On their second visit Ista confirmed that it was their fault and they apologised and fixed the meter however they have not responded to my requests about the refund of the extra amount that they have charged me. I have sent several emails but did not get any answers.

Hello Mr. Torkaman, thank you for taking the time to tell us about your experience. I am sorry that we made a mistake when installing your meter. This should not be the case. We are of course happy to check your bill for you if there are any discrepancies. In the first instance, your landlord or letting company is the right contact. Please contact them to initiate the process. We have also just sent you an email via Trustpilot. Please get back to us with your property number and address so that we can get in touch with you and find a solution. Kind regards - Lea from the ista team
