Absolutely pathetic cancellation department!

Absolutely PATHETIC service from Telkom! I cancelled my contract at the end of April for the end of May telephonically and was told everything was in order. Come end of May, Telkom debits me, so I reverse the money as I was told that I pay in advance and I wont be debited at the end of May. Note, I am NOT receiving data any longer! Telkom then has the audacity to hand me over to attorneys for an overdue account! You try to contact them and NO ONE ANSWERS!!!!! TELKOM GIVE ME THE RECORDING OF MY CALL FROM THE 30TH APRIL SO I CAN PROVE MY CANCELATION! I WILL NEVER RECOMMEND TELKOM TO ANYONE EVER! Imagine getting blacklisted for R99 that I dont even owe! I did not receive the data, what am I being charged for? the account needs to be CANCELLED!!!!
