Inefficient, poor and terrible customer service by Cellc

Cellc has until now failed to simply confirm the debit order of R2583.23 that they deducted last week on Wednesday 30th September 2020. Following my last complaint, Skumbuzo Ndhlovu has been on the case since Monday. After following up with the case on Tuesday, Thobile Ndlovu also **** to me by saying I just needed to pay R305 and she would assist in reopening the lines again but upon paying the same amount on Thursday, R305, she changed the tune that the system has just updated my owing amounts and it was impossible for her to reopen the lines. Subsequent to that, Cellc switched off even my other prepaid line for no apparent reason for the most part of whole day Wednesday and this caused me to miss a lot of calls including a potential employment call which has since been withdrawn by the employer. When I called in Cellc's explanation was that I instructed them to switch off my line but they have failed to provide me with evidence of me instructing any of their call Centre agents to block my prepaid line. Why would they block my prepaid line? What kind of service is that? I didn't ask for them to block my line but this just shows how poor and *********** customer service of Cellc is. Cellc has now caused me a lot of economic losses. Please help me. Is it because I am an African and they are taking advantage of me?
