Suspended PAID accounts, causing bad credit

My top up contract has been suspended, the debit order has been going off every month promptly. This is causing so much disarray in my life, I have sent the proof of payment numerous times, I have phoned customer care non stop, they are rude and unhelpful. I have been to the Vodacom store in Somerset West more than 5 times, every single time they tell me they will look into it, nothing came from it. I can not cancel my contract as I still have to pay until the contract finishes. This is poor and unacceptable service. I am in arrears as I can not make any payments without my phone, I can not receive any calls, I can not make any phone calls. This is such a big inconvenience and embarrassment to Vodacom, I am sitting with my hands in my hair and DO NOT KNOW WHAT TO DO NEXT as I have done everything I possibly can and still my line is suspended. Utterly disappointed, as I am a good client and Vodacom is responsible for me possibly getting bad credit for not paying my bills. Please Vodacom fix this and please stop this from happening every single month.
