Bad service

Good day

I am very upset about the service of Mweb.

My debit order was supposed to go off but I didn't have money in my account. I then proceeded to contact Mweb to arrange a payment the next day. I spent a lot of money trying to contact the billing department but I didn't get the help I wanted. I then paid the money into the bank account and used my account number as reference. Now they refuse to use that as proof of payment. I want my wifi reconnected.
