Pathetic customer service from Vodacom!!! Still Unresolved for Over a Week now!

Pathetic customer service from Vodacom!!! I called in last week Wednesday 28 August 2019 as Vodacom is charging me at a rate different to my price plan. I was told that it will take 3-24 hours for the problem to get resolved. After numerous dropped calls, referring me to their "Bot," the answering machine advising that the Centre is unavailable, to date my issue has is still not resolved!!! Their quick fix solution was to provide me with extra airtime however it does not change the fact that I am still incorrectly billed. After numerous attempts to contact them I get told by the answering machine that I have exceeded my attempts to contact their call center. Thereafter, on Thursday 05 September 2019, I had to call them from work and make a charged call to them. I asked to speak to a Team Leader or Manager to which I was presented with Themba. He then called me back and put Dimakhatso on the line who said she will gather all the information and call me the following day at 08:00. I am yet to receive a response from her. I am still experiencing this problem and am regrettably inconvenienced because of Vodacom's genuine willingness to assist me in resolving a problem that they have created. Could someone kindly help or do I now have to go to the OMBUDSMAN? I have been quite patient with this service provider and I have now run out of patience.
