Appealing Service

From the 15th my services were deactivated and the reason was the change of ownership and billing account. I now had to spend several hours telephonically trying to get the line re-activated and also through back and forth emails with no results I find this very unprofessional cause this line was working fine the only change was ownership and billing, I've tried my best to get this service activated, this is affecting my business financially so much and I find the delayed responses to be highly unprofessional, worst part is that my debit has also gone through, yet my line is going on the 5th day without internet service. I have spoken to several people namely a gentleman by the name of Mfundo Mnombeni from Vumatel who seems to be the king of empty promises, he has now decided to cease from responding to my emails.
