2nd line installation from SADV - non existing

The worst service i have ever received. Ordered a 2nd line for fibre 3 months ago thru Webafrica. Has now tried numerous times to get an answer out of them to no prevail. I have contacted Webafrica now 15 times already to get an answer on what is going on. They even phoned SADV while i was on the phone and said they will get back to me later that day. SADV just don't care. This was 3 weeks ago. Worst service ever or must i rather say no service recived from them
