I just want my money back, stop making excuses

On 9 October 2015, I was advised I would get my refund in 7 days. That would make it 20 October. No money came in, and on 21 October, I asked via email what was the delay. Then the day after I received a response to my email saying I need to phone the call centre and speak to the finance department. I called this morning and after about 5 calls, of maybe 10 minutes holding time each, I hear the system has a fault and was unable to process payment in time. I now have to wait another 5 working days for the system to get back up before the payment can be processed. This means it will take 15 working days (almost the whole month) to process my refund!? This is not fair at all. I don't believe that in all this time no-one knew there was a system fault for such a large company and no-one (not your suppliers etc) got paid in the last 10 working days! Regardless, the bank closes at 3 pm, someone can walk in and make a deposit! I want my money today, 10 working days have already gone, I will not accept another 5, stop making excuses. I really don't have time for this.
