Technical error on your system,my double debit

Making an error on a debit order is one thing,trying to speak to someone in the right department to sort it out is quite another story. Seems the technical problem you had with your Aug debit order,is now my problem. I am glad to see that your error allows you the freedom to take it upon yourself to take a double debit the following month,without giving your client a proper opportunity to rather pay you directly. I have logged countless queries, and I am currently holding, with nearly 20 mins and counting. Your Customer service is absolutely pathetic. All you offer to do is escalate the query for your DPP department to phone me back? by when? Probably when the ***s come home? the bank account you are debiting is not yours, and at no point does that entitle you to free reign, for an error that you encountered. Who d you actually think you are? Nobody can advise what your standard SLA is for sorting out queries of this nature? Do you actually know what caused the error for the debit orders to not go off.. probably not, because no call centre agent could supply me with this information either, probably the same way you wont know how to respond to this complaint either way...
