Bad Service from CFibre support at Cell C

I am very frustrated with Cell C’s fibre team. My complaint and issue has gone unresolved for the past two months. Cell C cancelled my fibre incorrectly due to their *********** credit control team who did not load my banking details which I provided in writing. The query has gone unattended for over a month while I remain with no internet service. Hatred and Neville from fibre support who are team leaders have failed to resolve this matter.
