Terrible service and total incompetence

Where do I start. Account was repaid and POP sent. Almost a week later and after many confirmations that it has been received, this month's account gets debited and last month gain. We have already struggled for almost 5 days to rectify the first issue and get the phone connected again, but now they just debit account left right and centre. Social media doesn't get back to you and no one at the call centre seems to want to help and rectify the issue. Where can I physically go to sort this out because you are useless. After this is will be moving elsewhere unless exceptional service is now received. This is unacceptable from such a big company. The service has been beyond useless and terrible. A few name of people who seem to not care about their customers who help pay their salaries: Itumeleng, Israel Stewart, Ula, Baetumetsi, Phillip, Talita, Candice, Tsotang. So guys what's its going to be. Help us or keep on wasting out time because you are ***********? it is so difficult to get in touch with you and get any service, please can I have an address and contact person to help me. Surely it cant be that difficult. Honestly now...
