Very Bad Service!!!!

I have never been this frustrated in my life. And I'm really not a person to complain but, the service I have received from Webafrica these last two weeks have been atrocious. I have been dealing with them for a while but recently had a payment problem where they canceled my services. I made all payments to reinstate it but then was told I had to order new services. This is going on for over two weeks now, where they just have to activate it again. But somehow that is thee most difficult thing to do, every day I have to chat to them on whatsapp because there's seemingly no phone lines. My previous ISP was SADV and now they tell me that Vuma bought SADV over. I've never had a problem with SADV but now I'm being left out to dry by VUMA
