Vodacom Customer Care Manager Refusal

I have had the worst experience with Vodacom ever, after being a customer for more then 15 years, I have always had good to say about vodacom but after my service today I will be cancelling soon with them, and I do recommend cancelling to anyone else having a problem with them. I have been debited more then what I was supposed to, after struggling to pay them for more then 2 weeks and waiting for a debit order to go through, I eventually had to go in to a store to make the payment and the payment was made from the same account that failed with them which they said there were no funds in... 2 weeks ago, I escalated to a manager in order to get my money refunded to my account, which was confirmed on call that everything will be done. I called back about a week ago to find out, and apparently nothing was done. I call back today, had the most rudest agent who dropped the call on me, and then also had a very reluctant "supervisor/team leader" who actually refusese to speak to manager when that is ******* and she makes excuses. The team leader was Tebogo Ledwaba and she blatantly refused me to speak to a manager and kept referring me to ***. The amount that was supposed to be credited into my BANK ACCOUNT as per the manager I spoke to 2 weeks ago, is only apparently going to be refunded into my Vodacom account and will take another 14 days to be refunded into my bank account for which I will actually have to call back again for, and when requesting to speak to a manager to get this sorted out right now, she refused. Advice to anyone that is using Vodacom, drop this service now. Now that they are busy losing more then R20bn they are looking for every way and angle to save money and cut costs even if it means losing their integrity towards their customers.
