Vuma/SADV bad service

I am based in Dube Soweto. I haven't had internet access since Thursday night 8 December. I have called the SADV call center to report the matter. I have called numerous times and was made to hold the line for 40 minutes for each call I made to them since Friday morning. After the voice prompts advise that you are 1st in line they hang up. I've left several voice messages requesting a call back on the issue. No 1 has gotten back to me still. I have tried online assistance to no luck as well as their whatsapp helpline. No one is able to assist me. This whole situation is really frustrating now because no one from Vuma or SADV is getting back to me to advise if there's a problem or what. I have just paid for the service on the 5th and now have no internet access. Guaranteed that they will cut off.the services as soon as the 28 day cycle ends regardless of me not being able to use the damn services as I have paid for them. I cannot get any work done and have the kids over for December and no one can access the net. So you can imagine my frustration. SADV call center service sucks in general trust me. This is not my first bad customer service encounter.
