Asianet Satellite Communications — wrong billing and poor service

Address:

Asianet Satellite Communications ltd, Chiyyaram, Thrissur, Kerala 680006, Thrissur, Kerala, 680006

I changed my digital box (Stb) in the month of august 6th 2019.. Paying 770 rupees and recived a receipt for that... After 2 months from then[protected] i was credited with 763rs in my account for changing the digital box again as clearly stated in the online transaction details shown in photos submitted... When i went to complaint about it they lied to me saying that its the amount i have to pay for the channels i am watching... Which is ridicules since the billing was asked from me for the digital box... I complained almost 3 times to their billing section in their main office in cochin and no result... Please see through the proofs i am submitting
