Inefficient Service by Customer care

I had a bonced debit for February 15. A week later a received a notification. I called Cell C to make arrangement for areas since I was not aware of a bounced debit. I need a 2 months arrangement of debit while my account remains active. I was told that such should start February month-end. I indicated that I only get paid on 15 so it should start on March 15. I was told that a great favour has been made already by keeping my number that far while the debit has bounced. I was told that payment is is expected month-end February failure which my outgoing calls would be barred. Since i was already fed up, i said please bar it as of now. The barring was immediately activated for outgoing call. Did the person realise that my contract is worth R1150-00 a month - a loyal customer not to be dumped? Shame on you Cell C Customer Care.
