Vodacom pathetic customer service!!

I took out a contract with Vodacom in September 2019. All my details including my bank account and address details was captured on the call. Not once did the agent indicate that my bank account would be debited within 7 days for the amount of the contract. I get an sms advising that my phone will be delivered however the delivery address is not the address that I gave the agent on the call, turns out they had my old work address and did not update it as per the call. I then get an sms advising that my account is in arrears. I call the call centre only to find out that they debited my old bank account and did not update the bank details that was provided on the phone when taking out the contract. They also went ahead and charged me R100.88 for a returned debit order. Obviously I refused to pay this as the agent never informed me that my account would be debited in 7 days. I then proceed to give the my correct banking details and low and behold they debit the incorrect bank account AGAIN and proceed to charge me another R100.88 for a returned debit order. I then called the call centre and cancelled my debit order and told them that I would pay my account manually each month to avoid all the issues. Today I get a bill of R328, 79 mostly made up of R100,88 for returned debit orders. I try calling the call centre but you hang on for over 30 minutes, when the call is answered you put on hold and then later required to rate the service but your query was not resolved.

I definitely did not expect this from Vodacom and I am very disappointed at the service received so far.
