Disappointed that Cell C cannot sort out the debit order issue after months

I have been phoning every month for the last 4 months to find out why my bill is no longer being deducted via Debit Order. When I phoned last month and I doubled checked that my debit order had been reactivated. The Customer Care Consultant assured me that my account would go off by Debit order. When I checked my bank account I saw that Cell C had not deducted the fees off my bank account. The Customer Care Agent that I spoke to today advised me that Cell C had a technical issue but could not advise when it would be fixed. It has been months now. This really is very poor service from Cell C!! Shocking to say the least.
