Worst service ever from Multichoice dstv

I payed my dstv account on thursday through the payat link on whatsapp. I called for them to reconnect my chanels and they said i should send proof of payment....which i sent countless time but no help.when i call they make me hold for 40 minutes and cut the call and they never phone back at all.ive called more than 10 times and the consultants put me on hold and cut the call.ive received the worst annoying service ever.i dont want anything to do with Multichoice but they must refund me the money i used to call them and for my subscription
