Fraudster company, ships counterfeit components

These people are fraudsters, they have an umbrella of fake companies: weekous, elecsemi, Cstronic, chipswill, sonteen , Chip Circuits, Ohto Tech , Icstronic / ICSTRONIC Components.

I have already reported them to Hong Kong Police.
They didn't deliver me goods after 8 weeks , and after exposing their fake business by email they shipped me counterfeit chipsets.
Report them to all electronic broker website and mostly to Alibaba, this is what I did.

Chinese authorities must close this fake business and put the owners in jail.
Don't Buy any product from them.

Suspicious company

They have a Shop on Alibaba, I have contacted them regarding a purchase asking for clarification over their certifications they display (blurred certificates). No response. Indeed there are some troubling information regarding the various turnovers they display, the phone numbers and addresses.

These people are fraudsters, they never deliver goods

This is a fake business, these people are fraudsters. they don't deliver goods ordered from them.
They are running several fake business:
- Chip Circuits
- Ohto Tech
- Icstronic / ICSTRONIC Components
- Weekous Technology
- Cinkochip Technology

They will provide you great prices for obsoletes electronic components which are very hard to find, but they will never deliver.

Their phone numbers ( UK and China) are not working , if you make a google research on their phone you will see it's the same one used everywhere.

Don't buy products from them.
