Poor service from Vodacom.

I made an online payment on the vodacom app last month on the 25th of May so that the money wouldn't be debited from my account on the 1st of June, for some reason that time the payment didn't reflect. On the 31st of May, I Went to a vodacom shop and was told to call ***. I called them and was told to send the POP to ***, I sent it same day, next morning I received an sms to send it to *** and I did that and there was no response from Vodacom and a debit order still went through on my account . I then called on the 10th of June because I saw the payment still hadn't been allocated and the consultant told me that she had escalated the issue and would call me back within a few minutes I waited an entire day until I called again and after being on the line 18 minutes and was told that they had received my pop and it was accepted and it would be allocated within 7-14 days. Because I saw that there still wasn't anything happening I called again on the 22nd of June and after being on the line their consultant for 18 mins she promised to call me back as she had escalated my issue, today is the 25th and I still haven't been called back. The amount I had paid was enough to cover last month's amount and this month's debit and they are gonna want to debit my account on the 1st but they are simply failing to allocate a payment.

I don't know why I have to continually hound vodacom sort out this issue which could have been sorted a long time ago. I'm glad my contract with them is nearing an end and I've decided I won't be renewing because of the poor service I received.
