Dear Sir/Madam,
I have been receiving calls from your Call Centre regularly on my DND number for Dongle selling/up-selling. This is continuing everyday in spite of my repeated warnings. Today I have received call from [protected].
It is my humble request to stop this from happening with immediate effect, otherwise I will have to complain at TRAI level.
Thanking you in anticipation of your co-operation in advance.
Best Regards,
Arghya Das
