Irregular debit order

I have an existing contract with Telkom which I opened at istore for a device. They debited me correctly on the debit date but then debited me again which was an irregular debit order of R1878.20. I called in and was assisted by Mandisa Cele who was kind and willing to help but seems to have a manager or supervisor, Menzi Ngubane who’s not so customer caring, to summarise all of this I didn’t get any tangible solution. Menzi said that he will get to my matter when he gets time which means that I must expect it not to be resolved it could go either way. I am not happy with Telkom there’s a lot that’s wrong in a short space of time and when customer “care” isn’t caring at all it makes matters even worse. So if you’re thinking of taking anything telkom please take some time and think about it
