Pathetic Customer Service

I took a wifi contract with Telkom in November 2019. I was told that my account would be debited every month, however, they have never debited me. I've tried the online helpdesk and I've been to the store in Chatsworth Centre about 3 or 4 times to correct this and still every month it's the same problem. In June 2020 I went to the store again and was assisted by Prabashnie who advised that the incorrect account number was on their system, I had to get another bank statement to correct this and was promised by Prabashnie that the issue would be resolved. Now, one month later, I haven't been debited and my wifi has been cut off AGAIN. I have tried my best for months to get this sorted out but none of the staff seems to know what they're doing and are unable assist me. This is no fault of mine, I've had to deal with useless employees and Prabashnies attitude and I'm still getting no where. This is the first contract I've taken with Telkom and due to the ridiculously poor customer service I will not take another contract or purchase anything else.
