I have a valid tatasky provided voucher worth rs 500 in vlcc. I am availing it from last 3 months and each time during payment they denied at first and after some altercation sometimes they accept the voucher according to their wish. On dated 11th june, vlcc kakurgachi denied to accept the voucher and said that their system is not accepting the code as everytime the code provided by tatasky is same, though transaction id is different. While i call to tatasky they said to send them the screenshot of the error vlcc is getting which they to provide. I am attaching my tatasky voucher and vlcc bill. Hope this kind of cheating with customer can be prevented.
