Ridiculous Response Time for Business faults

I reported a problem with our ADSL on Tues and was told that it must be a Telkom problem. Fair enough, called out Telkom who checked all and we tested the line via their guest account and it was functioning fully. How ever when connecting via MWEB the speed dropped from 9.7 Mbps to 0.35MBps or just comes up with Latency error. Called MWEB Thursday to report. Was told it needed to be excalated to their technical division ref mwb ********** . Friday called to say no change. Was told that it I had been given a slot for Sunday! How can they accept that they can only get to look at faults 4 days later! Ridiculous, I lose money when not connected, so will have to look at other ISP's and this after 9 years as a customer.
