Utterly disgusting service

I am utterly disgusted in the useless and *********** service I have received from Vodacom. I have been a customer for 20 years. In September, Vodacom wanted to charge me an extra R6000 on my account because I did an upgrade with their sales department and the ***** who did the upgrade implemented it immediately instead of from the new month as he should have. So I was being charged for my current contract and the new contract in the same month. I disputed the additional charges. No one called me back. I followed up 2-3 times per week. Every time I called, no one knew what was going on. Five weeks into the dispute, suddenly all my lines get cut. It took a huge fight and back and forth to get anywhere. I got told to pay one amount to get reconnected, which I did, but nothing. Then I get told, no that’s not enough, I must pay more, so I do, then I get reconnected. Another week passes and I get an sms to say my dispute has been resolved. I carry on with my life. Today, my fibre line and my one line get disconnected again. I call and a very helpful consultant on the mobile side tells me oops, we forgot to remove the connection barring. She removes it and all good on the mobile side. I call the fibre side and they say, nope, can’t help you, the account in arrears. I explain the whole story to them and they pretty much say, not our problem, have a nice day. So, the sales dept **** to me, the accounts dept **** to me and the dispute dept **** to me. Worst of all, they don’t have the time to call me, I must chase after them, but they are extremely quick to disconnect lines without investigation or question. It’s shameful and a gross misuse of power.
