Poorest service in South Africa

My phone was blacklisted by vodacom due to non payment... I then settled my outstanding amount, I then called vodacom to reinstate my services they told me to go to the shop. I went there and filled the unblacklisting form and the IMEI number of the blocked device ' then I was told to switcb of my phone for 24 hours and I did as told. After 24 hours my phone was still network locked. I contacted vodacom again, I was sent to the accounts department where I was again told to switch my phone off again, I was patient and did so. Suprising my phone is still blocked and its more than a month but the bank deduction are still going through but no services . I am tired of calling customer care daily for the past werks and fslls promises are made. I waited for the supervisor to contact me till today I haven't been contacted by the supervisor. All I get is the same promise everyday. I have lost patient and need assistance in resolving this problem. Vodacom has a poor service... my device is locked but debit order for payment goes through. I have vodacom and want a refund for the money they deducted, and they must take this device out of my name and terminate the contract with them asap. I have lost patience
