Horrible service

I have a problem with Vuma service provider called SADV I paid my Wifi on the 8th March it was switched off on the 10th. The number they provided to contact them is not working, I've sent emails no respond the whatsap communicator they are using will ask you to provide bank statement while you do that it is cut off you are told you took time to respond. You have to start over again I provided proof of payment, bank statement 12 days today still no feedback I don't have a wifi I paid for and is the middle of the month now.😉. Tried the whatsap communication again yesterday the person responded and told me there was no record of my query promise to escalate the query to date nothing has been done. She told me next time when I make a payment I should go to the shops do not do EFT imagine 2024 this company still want us to make long queues in the shops.
