Sick of MDB *******

Ive made a payment according to my arrangement but with no avail they never disappoint with the harassing calls and smses and apparent legal documents and court summonses and frankly im sick of it now, i will not agree to a debit order again as they completely follow their own way on your bank account. Since stopping debit orders and making eft payment now suddenly suddenly "dont receive payments' 'Did not honor" bunch of ******* if you ask me, no reaction from management if there is even managers and if I phone them i get a clueless response of " oh ok mam" and nothing further. Frankly sick of it and will stop payments.
