Worst customer service

I ordered a 2nd line for a new address on 15 Sept. Vuma called me to arrange installation but because their T$Cs state that there should be no construction work on site when they come to install the fibre line. I had to postpone the installation. 17 Nov I reached out to WebAfrica advising that I was done with construction and needed a new arrangement to be done with Vuma. I spoke to Sikho S and he assured me a ticket was logged with Vuma and I should expect a call from them. A week later I followed with them again and I spoke to Arezona who told me Sikho B couldn't log a ticket so I accepted. 5 days later spoke to Arezona and she also assured me my request was sent and I should await a call from Vuma. Today I have been on the line with Jeanette M and after waiting for 1 hour to get someone on the line she took 2 hours to tell me the installation was cancelled and a refund will be processed and she apparently transferred me to Billing Dept and Sfundo S took over the chat and he advised they could just place a new order and reallocate the funds to the new order and only later to tell me it cannot be done. 1 hour later he tells me Invoicing takes care of refunds. I am now on the same with them since 10:37 at the time of writing this review and I am yet to receive any confirmation email for my refund. I have given them my banking details for the refund to be processed so I can place a new order. It makes wonder if I can carry on given them business. The level of incompetency is beyond me.
