Bad Bad Service

I have just had the worst service from Telkom ever! 3 of your sales people came to our offices and offered me a 20MB VDSL line. I asked them several times if there is coverage in my area and they confirmed that there is. They were suppose to upgrade my line today. When I phoned they said that the order has been cancelled. They say they could not get hold of me to confirm my address. I AM AN EXISTING CUSTOMER. They should have it as there is a Telkom line in my house already Then they said they would create a new order for me and I agreed. Just after the order was created they said to me that I can not get the 20MB line where I live. I spoke to a supervisor Tabiso. They could not confirm anything to me and said they will get back to me on the speed. This after I was assured that the 20MB is available I cancelled the order. This after I was on the phone for 40min. If I had another option other than Telkom for a fixed line, I would have cancelled everything that I have with Telkom right now. Bad bad bad service as always
