Poor unpleasant customer service

I have received the most unprofessional and unpleasant service from this network provider. I first contacted Cell C via their twitter acc-direct message,on the 2nd Oct 2021, was told that I'd be assisted, I waited and still waiting. I have sent countless emails, I have called,twitter..but to this day,no assistance. I've been thier customer for years, and needles to say this is not the first time I am given the run around. My account is in arrears and wanted clarity regarding payments and all of that, but instead of being assisted, My matter was chucked to the side. It's month end now, I obviously need to pay, but how do I go about that without being assisted on the said matter? Or is this how customers who are in arrears treated, maybe? From the "YM" consultant on their twitter account to Nelly and Monwabisi Pambo on their sm email account. Unprofessional service.
