Disgusted with service for vodacom

I'm super furious now with vodacom. Their call center agent are so rude they don't update the information when you contacted them with regard to something they did themselves. Last month I have to pay my contract phone amount of R7600 because they decided to cancel my debit order that has been there for almost 6 years. They decided to hand me over to collections when it's was their fault. I visited vodacom shop to pay that amount I asked them to reinstate my debit order or rather email me my monthly statements but no they didn't bother. Come my pay day they didn't debit again. On the 18th of August I contacted them asked them what happened they said they will run it for the following day. Today on the 20th nothing again still reinstating my debit order . This is so disgusting I wish I can cancel their contracts.
