I am surprised at this much progress
My current complaint through TPS received the following reply
It would appear that **** are misrepresented by a company using the same or similar trading name and/or spoofed their telephone number. However, we have not been able to positively identify the offending company. Please note that TPS does not have the facility to track or trace telephone calls that you have received.
I have replied with email received from them with headers that clearly show the company involved.
But to do this I had to convince them to send me an email.
Most of the Indian call centres used spoofed numbers and TPS are powerless to follow up. I get 1 to 2 calls every day, I string them out to waste their time and try to get them to send an email to get some evidence.
The government need to force carriers to use technology that can verify or track back numbers. This would also stop a high percentage of fraud carried out by telephone.
