Returned Debit Order

It has been almost 24-hours now since I requested assistance with returning a debit order. I have received various e-mails stating that someone is attending to the query and the matter has been escalated but no-one calls me. They asked me to provide a contact number and skype details which I did but still no-one calls me. I am overseas at the moment and wont be back for some time so calling into the call center all the time costs money and they are not quick at answering or resolving queries so a 15 minute call is the norm. I just want someone to call me on this number +353 87 ********** urgently to resolve this matter.
