Falsely accused of being in arrears

Vodacom, placed my account in areas each month, when they can't debit me on a weekends or public holiday. NOT MY FAULT!!! I have NEVER been late with any payments for Vodacom and have proof of my bank statements! The other thing to notice here is you are *****ing up my credit score by falsely placing me on arrears each month when the fact is that it is due to your outdated primitive system which can not distinguish when a person is actually late or when the debit order falls on a public holiday or weekend. Again, kern your **** Vodacom! This happens each and every month. If you do not solve this once and for all I will SUE you for falsely accusing me of not paying. Fix your ****! Test me!
