MTN again

Actually it should be 0. I am so sorry I ever did business with MTN. Today I received a call from their collections department to ask when I will pay my account that is according to them in arrears. When I checked on my MTN app it shows that I have no outstanding balance that I owe. They do not send you invoices or statements and today the call center told me that their debit order system cannot accommodate my bank so I must to the payments myself. What a pathetic service provider. This is not the first time I have issues with them. I cannot wait to end the contract.
