Dstv is been charging me for an upgrade i did not do . i phone the day they disconect my dstv. send me an sms to pay 800 and something and the said i have a self service upgrade for tv that i don't watch . so did upgrade 0n the 6 and on the 14 i cancelled that is according to them, when you we watch the channel you did not call us. How couse the chanel was open for evryone recenctly. On the 14 feb 2022 i paid 380 some and on 1 march i paid 350 on the 8 march i paid 399. All those transaction on the name of upgrade i did not made. I ask them to prove for me that i did .i am willing to even to give my my device ip adress to prove i did not do it. At my work i have cctv to prove i was at work if they want anything i can do to prove my self. All i want is my money bck you can not take my money without proving my innocent. I spoke to 3 people already on this matter. I told them the must tight their security for us .dstv self service is costing us customers.
