Telkom nightmare

What a nightmare since I’ve joined when it comes to debits , apparently the reason why I keep getting rejected debit order is the mandate was not accepted so for all the months I have been with Telkom I’ve been charged rejected debit fee , agents are not transparent nor have a solution to your problem. I’ve asked to speak with a manager which I can not as they are working from home , asked if they can get all my call recordings to be sent to me so I can escalate myself , the agent can not assist with that too . Some problems have I’m being told to go in store which they referred me to call Telkom. I am livid for all the rejected debits I have been charged , I want that money back all of it also I just cancelled my mobile insurance them which I was told about pro rata which I asked how much will it be , the agent said he doesn’t know. Please refund 3 months of those rejected debit orders as it was not my fault the mandate was not sent to me . You do not even deserve this one star
