Bad Service

My network went down for 45 minutes this morning from 10.45 till 11.30. I teach English online and due to not being able to get through to RSA web I had to cancel my lessons with my client in China, which has resulted in a day with no income. I managed to get through to the call center at 12 pm and spoke to Ayanda. She said that on their side it shows my line was stable, therefore she cannot assist.

I am paying for 10Mbps download and 10Mbps upload, which is supposed to be unthrottled and stable. Quite often my upload speed drops to 3.28Mbps. Ayanda could also not give me an anser for this.
