worst customer service and double debiting

called Telkom to rectify my debit that was done and was told they can only rectify it within 7- 14 working days, Firstly service is poor Mbali Mo***eng told me there is no manager available to speak to or team leader, after a threat then only she transfers me to the team leader ( Masilo Mohale)who is also more useless and needs motivation to come up with a solution to the problem... Only after me suggesting they escalate this to his manager or to their back office team, he then only gave the solution to the problem.. which what he was supposed to do initially... not sure if the guy knows how to assist clients or if he just listens to what the agents are telling him to say cause he was not only useless he sounded clueless as well. where is the customer service.
