Bottom of the pits service!!!

I'm really frustrated with this service provider! First I topped up my data using MY money and they had the audacity to add the top up amount on my bill for the coming month, when I had prepaid for it. When I called to query this, I couldn't get help. At some point they told me that the money had been credited back to my account, but came month-end, dololo credit! For months I phoned but did not get help with this and I got tired. Beginning of October I gave notice for my account to be canceled but then reinstated mid-month. I didn't get a response for my account to be re-instated, so I phoned....and as always held forever and when they finally answered, they couldn't assist me so they put me through to another department, which never answered until I hung up. On the 25th an amount of R399 was debited and when I phoned to query why, I was told because I had reinstated my account, and that this was the bill for November. And because I still have a credit of R150, that's why I was only billed this amount. So then they confirmed that my account is still active and I can continue using their services, great! Well, this happiness was short lived because today, I have no WiFi! I phoned, again, to inquire and needless to say, I was not helped because they couldn't understand why I was billed but my account not activated! I was then again, put through to another department and I continued to hold with no response. 30min later, I'm still nowhere to being assisted, airtime exhausted and I really don't have the energy for this level of incompetence. If you guys don't want me as your customer, please give me my money back and I'll make alternate arrangements. I'm really tired of this nonsense!
