Charging clients for services that were not provided

Webin CC gave notice to have 3 lines cancelled on the 6th September 2017. On the 12th September, Telkom disconnected the 3 lines yet still billed the company for the three lines. Due to the 3 lines not being operational payment was not made for these three lines for the month of September. On the 5th October a dispute was logged with Telkom regarding the three lines that were not operational yet charged for. The company then gets billed a further R822.12 ex VAT for a "Service Fee", again for the three lines that are not operational from the 12th September. Now Telkom further to it lack of efficiency has suspended the remaining service to the company. So in summary, the company has been charged R786.84 and R822.12 for September and October for 3 telephone lines that have not been operational for these two months and to make things worse now have the other business lines suspended. COMPLETE INCOMPETENCY!!
