Worse service

Worst service from Telkom they went to debit my account with incorrect amount as per agreement, when calling to question debit order I being sent from Pillay to post spoke to Nompumelle Dlamini shame she can’t help worse her team leader or manager not will to assist her and she is told not give name of the team leader, all I want from telko is to refund me what is due to me and stop blaming other departments within the company I don’t wrk for them
