DONT BOTHER CONTACTING ME MTN - EVEN TELKOM IS BETTER THAN THAT

MTN had an issue with debit orders in December 2019, my debit order date is the 1st, in that month the 1st fell on a Sunday and as always the expectation is the debit order would run on the Monday night being the 2nd, this did not happen and they landed up debiting me on the 4th only, this created issues for me and i notified and sent them an actual bank statement to prove my bank issues and costs, the responses received back have been anything but bizarre and shocking to say the least, the individual assigned to email queries is absolutely illiterate and cannot read factual info and MTN have turned around and said the debit was correct and I am at fault......I'm shocked but getting no where with the endless emails and Id rather move to another provider whom will do as i ask and debit me on the correct days without causing bank issues for me and additional unnecessary costs.
