Charged for calout fee when Telkom ADSL lines slow

Line kept dropping. CalledTelkom and they sent out a technician. Technician advised that I am only getting a 2mbps speed and line keeps dropping because I am 3.4km away from the \box". I will never get 10 mbps. It is impossible. Telkom Sells 10mbps lines when they know you will never get that. He advised me it would work better to bring the line down to speed 8. He installed speedtest app on my phone and he said based on him changing it in the background to 8 I will now receive max 5 -6 mbps. He also informed me that I should keep on paying telkom for the 10mbps line because if I pay for the lower service then it will be worse and I will get a 2 - 4 mbps line only and this is unfortunately how TELKOM cheats their customers. I received my bill and now I was charged for a unnecessary call out fee and the finance department refuses to give me a refund. I was holding on for close to 40 minutes and spent money on a call as well because they do not know what they are doing there. Bottom line: Telkom doesn't give you the line speed you actually pay for. When you complain they are able to \""fix\"" the issue by lowering the speed and line you pay for. But you have to pay for their call out fee"""
