Vodacom Incompetence

I am sick and tired of Vodacom not following their processes. I made eft payments on my account and the departments never communicated with each other and then just cut my line after many many times I told them I paid. I sent them my pop and received an email from their pnr department to confirm my account is up to date and will only be debited end of April. Come end of April, they do not debit and instead they kept sending me emails to say I am in arrears. I have called and have an extensive email trail to back up everything. The more I email and CC their pnr and pop departments, the less they seem to understand. I am now only owing for the month of April which they have not debited. Now my credit is in jeopardy due to their own mistakes. I have proof of everything and think this is ridiculous. This should be sorted ASAP.
