Shocking Telkom Service

I have not had internet connectivity since 26th July. Called several divisions at Telkom, from customer service to their technical section and kept getting sent from pillar to post and then to Vumatel who installed the fibre. Seems like the Telkom agents did not have a clue as to what was going on with my account. They kept saying it was cancelled but I never cancelled. So after 2 weeks of not getting any response, I cancelled and moved to another ISP. Now I receive a massive bill from Telkom for service I did not receive and they have not had the decency to respond to any of my emails. Yet they have the audacity to bill me! Now I have to waste my airtime and time to resolve this problem.
