Poor Service, *********** staff and wrongfully billed

Telkom has terrible customer service, I've been querying from Feb 2022 regarding a double rejection fee for 1 unsuccessful debit. Every time I call in or request for a callback each consultant ends up dropping the call without assisting me, they don't escalate matters, they don't assist if you want to speak to a manager either, I've sent more than 10 emails with my statement and not 1 consultant has attached it to my query and till this day there's no refund. Pathetic service provider. Not one agent can do their jobs. Neither does management check if their staff are doing the right thing.It is disgusting that a service provider can give such a service.
