Poor customer service

Poor customer service . I called to change my payment date and the lady i talked to said it was done. Then i wake up today and i get this sms "We've stopped your DStv as you've not paid. To reconnect, pay R504.09 using ref no. Once paid, we'll reconnect you. To pay: payat.io/dstv/. " after i communicated with them . I call the call center again and i was told they can't help me.
