poor service delivery

I am so angry and frustrated by Telkom Eastgate for their poor service and handling of customers. I app**** for an uncapped data plan in Dec 2019 and was given a sim card that never was activated and never worked , surprisingly they went on to debit 2000 for that service that I never used, i went back to the store in Eastgate and demanded to speak to the manager Cathy. she tried to do as if she is helping and we all found out that the line was never activated since the day I received it.she said they are going to do a sim swap so that the line can be activated and gave me a ref advising me that it was going to start working but it never did. the following day I went back telling them that the line is still inactive a was told to expect it to work form Mon since it was Sat. I waited and nothing happened till I called the call centre with the ref and surprisingly was told that the line was never activated and they just gave me a line which meant they only wanted me to leave the store as there were many of us with same complain. the consultant then said he is restarting to capture my details and within 24 hrs a sim swap will be done and my lie will e active but till now the 3rd of April there is nothing, they even debited another 2000 on 31st march for the same service I never used and m being tossed from pole to post regarding this matter.telkom needs to refund me the 4k cz I never used their service and I don't have even a number for that.i gone through serious losses through lockdown because of their empty promises. Our business runs in 164 countries we could not afford such unprofessional service . We need our refund as urgent as possible and nothing to do with Telkom. After that, we are cancelling every line and contract we have with them upon every branch nationwide through this reference.All 9 accounts jhb in our business will be closed with immediate effect.
