SERVICE PLEASE VODACOM

I changed my email address almost 2 years ago. On the website or when I call Customer Services they have the correct email address. However I was sent OTP about two months ago as I forgot my password. I never received it. A few days later someone from the company I left forwarded the OTP, they still have my old email address. I called Customer Services and after talking to them for about 20 minutes they said that they would refer it to the back office and get back to me. I never heard from them so I assumed that they had corrected the email address. However about a month back I had to purchase more data and lo and behold the invoice was again sent to my old email address. That is problem number one . The other problem is that I had dropped calls a week ago on Friday. I received an sms on Saturday to say that due to the dropped calls that I would get 10 free minutes if used by 11pm on Sunday. Later on Saturday I had a calI for 15 minutes but have never received the 10 free minutes. I called about both problems on 10th October and spoke to Leticia who said that I would get a response within 48hours. I NEVER RECEIVED ANY RESPONSE. I called on Friday morning 13th October and spoke to Amanda who said she would escalate this and get back to me. She did call later on Friday only to tell be I would have to wait another 48 hours, unbelievable. I told her that I had already waited 48hours how many more 48hours would I have to wait, she could not answer. As of now still have heard nothing. AGAIN THIS TOTALLY UNBELIEVABLY BAD, BAD SERVICE WHEN ARE WE IN SOUTH AFRICA GOING TO GET OUR ACT TOGETHER AND SUPPLY BETTER SERVICE, HOW MUCH LONGER DO WE HAVE TO PUT UP WITH THIS?????
