DStv robbing people

I was given a explorer when I move in to my new place and I had to change my old account to the new device for future use as the complex rules only allows explorer so we called dstv to assist us the lady on the call assisted and said my account was not paid she will only activate it for three days if I dnt make payment within the three days they will cut it and by that time I was not using it, I just needed to setup so I ddnt pay. now Im getting calls saying I owe DStv money because they ddnt cut it after the three days so how is that my problem while we ddnt have an agreement for them not to stop it and I ddnt know it was still playing. Till today I haven’t used it.
