Bad service and unfair charges

I have contacted them several times regarding not receiving calls or making calls on my mobile contract. Nothing has been done. It takes 45 minutes getting to the call center and the staff is ***********.

Secondly after calling them and changing my banking details Telkom still charged me for the unpaid debit order

Telkom has been a servere disappointment to me . And I've been with them for 4 years . Their services are ridiculous now
