Incompetence of Cell C staff (Accounts department)

Cell C clientservices and especially the accounts department is the most useless and managed by totally *********** staff. I am a client since 2003 and the monthly subscriptions are paid by debit order from my bank account. However for the past 4 months I regularly receive notifications that my account is in arrears and this even resulted in the service being disabled. Numerous telephonic conversations followed and eventually the attendant at client services apologized for inconvenience caused and reassured me that my account is NOT in arrears. Needless to say that I again received notification of being in arrears and my request for an upgrade is not approved. However on the system at Cell C shop it shows that my account was never in arrears. Very frustrating to deal with *********** staff. Cell C cannot be recommended as a service provider.
