Poor service

My husband took a contract phone with Vodacom he gets paid on 27 if it falls on weekend he gets paid on Friday which vodacom was informed about this but still they debit on a Monday and late in the afternoon.due to the pandemic times are tough for us then we took the money paid cash on Monday 28 to avoid skipping payments but no vodacom has the nerve to tell us we owe them for a debit order that failed an amount of r100 I mean why didn't they take their money on time and you pay cash still they send a debit.

Their service is poor and we never and never again going to do business with them ,their service is poor we even tried to explain why we paid cash but they not taking that all they want is the penalty fee of which I still don't get what is it for because we paid on time Vodacom is robing us.
