Hi Magpie - I saw your other thread too, perhaps they should be merged?
The person I spoke to in UB (senior complaints manager) told me that they had in fact been presenting the DD every month since I cancelled it and that AIB had prevented them from "pulling" the money from my account. I told her that I had sent them a copy of the letter to AIB cancelling it and was advised to send them another letter cancelling it again, basically because they didn't bother reading it last time.
AIB confirmed that they would have rejected the DD attempts each month but that because the sepa system uses a different "door" to access the accounts UB bypassed their refusal. AIB are in the process of refunding the amount.
Bronte asked on the other thread how you blacklist a DD originator - the person in AIB gave me a form to fill out which has various levels of restriction for all DD originators or certain ones or indeed amounts above a certain level. Ask BoI for one.
I still haven't had a response (other than "thank you for your patience while I investigate") to my letter of complaint last November about their wrong DDs but AIB person said I can go to the ombudsman without a final response if they take more than 40 days. The ombudsman is so slow I've decided to give the new Complaints Manager 2 more weeks before going that route - she might be better than the last one!
I think they need to either clean up their act or hire a few hundred more Complaints managers.
