I am consumer of videocon d2h my id[protected]and facing a problem of their fraud
I am paying 385 for that channel which i didn't even purchased but when i ask the brand about the info about my purchase of that channel they told some times it happens in their system and i have again asked about my picked actual amount of the channels and my actual cost is rs.320 so from 3-4 months they were unusually charging me 385 without my permission they add some channels to my pack and has no info about when i had told them to select the package
And they told that they are not liable for that mistake so is it i am liable for that mistake??
