CellC Fibre to the home(metroFibre)

CellC Fibre- I am utterly disgusted at the lack of service I have been getting from CellC fibre! There’s a call centre agent by the name of Nontsikelelo,very rude and also places me on hold for lllllong periods,unholds call and keeps quiet! I made a manual payment on the 1st of June for my account and they have failed to allocate the payment after numerous escalations and sending proof of payment! CellC keeps trying to double-debit my account when I don’t owe a cent! And this is messing up my credit score as the debit returns unpaid!!!!!!!!
