Irate customer

I am very disappointed in the service of this service provider. I had WiFi installed by Vumatel on the the 19th April. I was told it takes up to 72 hours to be activated. Which I didn't mind coz I knew it was the Easter weekend. I wasn't ask which service provider I would like. After several emails to Vumatel last week they messaged me to say my line is faulty and send techniciandls to fix the line. I had to wait another 3 days and eventually the line was fixed and SADV was my service provider. I was send my username and password on Friday with an SMS to say the line is active and I can make use of it. Which was a lie. Since Friday I get the message if I want to connect the ( connected but no network) I've sent several emails to SADV with no reply just a lot of ticket numbers to say the fault has been logged. Their times show their customer services are open 7 days from 7am to 7pm. And still no phone call or email reply from them. I paid my full subscription for April. But have no use of something I paid for. If this is how their service is at the beginning. I won't advise anyone to do business with them in future. I would then prefere to do business with MWEB. Coz I only hear great feedback if them. I am really disgusted in SADV service
