Poor Custiner Service From Bonitas

I have found the customer service from Bonitas very poor. I signed my mom up in September, paid the first month via Eft and submitted my banking details for further payments to go off as debit orders. I noticed in the beginning of October that the contribution debit order had not gone off so I emailed to query, they said it had gone off, a few days later I got an email stating the membership had been suspended due to contributions not being paid. I contacted them and they said they had the wrong Bank listed on the payment account. I resubmitted banking details on the 14th of October, have sent 2 follow up emails which just resceive the standard automated response. I called today to follow up and basically they still have the wrong account listed and said they would "escalate it" with no clear indication on how or when this will be done.
