Herotel -Bad service in accounts department

I have a problem with this company Herotel that supplies wi-fi services. My name is Zukiswa LCZUK044. Today i got email that is threatening to suspend services because they say my debit order was not paid. That is a lie because my account was debited with the amount of R549 on 10/01/2024. I had to send them a screenshot from my banking app because my bank doesn't provide proof of payment for debit orders you only get one when you make an eft payment.

I am not comfortable sending my bank information to them but I sent them a screenshot anyway so that this problem can be solved

My problem is herotel is using the same bank as me which is fnb but now and again I get the same problem with them telling me I haven't paid even though I have. I waste my airtime phoning them & the bank because of their inefficiency in doing their job. They want me to send them proof instead of checking their statement or fixing whatever problem they have with their systems because they are the ones who want to be paid by debit order now they make me spend money in phone calls trying to make sense of what's going on.

I am not impressed at all with their accounts department, they dont know how to work efficiently and not make their customers as though they are at fault
