Bad service provider

Router problematic, speed not what ordered or paying for, not much help from the call center, technician came tested the router, found it faulty loaned me his and it worked at the speed I paid for, he recommended I go to a Telkom shop and have my router replaced was told at Southgate, the Glen I must go to Midrand from Ennerdale to have this replaced 🤯, he collected his route 3 months later and lo and behold back to connected with no internet, called call center they cannot help call logged and they will get back to me in 48 hours it is Saturday so I expect a call on Monday, not the first time and probably not the last for this type of service can't wait for my contract to end
