Poor customer service at dstv

Thumbs down to dstv payment section. Just queried our balance. We are over R1600 in credit. Dstv say their system is problematic, has been reversing payments in error. And as such, reversed our payment of R1000. So we now owe abt R321.00 In order for them to correct our balance we must now send proof of payment? it is 37 degrees in pietermaritzburg today... I must now drive to nearest service provider to scan n email proof of payment. Yet dstv can clearly see my payment on their system! What nonsense. Everything at their disposal and it's their fault system reversed our payment but I must now be inconvenienced to correct this. Come on dstv, we pay diligently (and extra every month). You accept our money, enjoy the extra interest and still expect me to sort your inefficiency....so not fair. Use logic n customer service n correct yr mistakes n appreciate yr customers please.
