Impossible for anyone at Vodacom to allocate a payment to my account!

I made a payment on my Vodacom account on the 28th of December 2017 at the Vodacom 4U shop in Cape Gate shopping center.The payment was never allocated to my account. After phoning customer care I was redirected to the accounts department and advised that I should send the proof of payment to ********** did so immediately but after 2 days,still no payment allocation.Phoned them again and was told the same.I sent it again,this time from two other e-mail addresses whilst I was on the phone with the agent.He did not receive anything but promised to phone me once he did.I am still waiting... They then contacted me and advised me that my account is in arrears after which I explained the situation and was then told to go back to the Vodacom outlet where I made the payment because they won't be able to trace the payment otherwise.I did this immediately.The agent at the outlet made a copy of the till slip and said that he will have to send it to the accounts department.Needless to say I was ecstatic!He promised though that it will be sorted out in 48hrs.Imagine my surprise when after 48 hrs the payment was still not reflecting...I then went back to the shop and was helped by another agent.This time I was more hope full because after disappearing to the back and returning she assured me that the payment will reflect after 2hrs and that I should phone her if it doesn't. Reason for the whole misunderstanding was that the ********** e-mail service was down according to her. Next day,still no payment reflecting so I phoned and was then helped by another agent.He took my contact details and the transaction number and promised to come back to me...still waiting.So I phoned again,same procedure and still waiting whilst receiving messages daily of my account being in arrears.

You have the most *********** staff I have ever dealt with in any organisation Vodacom and I will be taking my business elsewhere as soon as anybody can tell me how much I have to pay to get out of my contracts with you.
