REFUND PROCESSING

I hired a car from Europcar and returned it on 31/10/2015. I received an invoice the same day to show amount to be paid back into my account and that it would show in 2-3 days depending on Bank. Today is the 11/09/2015 and still no money in my bank account. Been speaking to different consultants on *** and being told different stories all the time. This is unacceptable for a big company like Europcar that I'm given such a run around. This was my first time to use Europcar and I wouldn't recommend to anyone to use them if this is the kind of service one would receive afterwards. No one bothers to at least contact the customer to advise of any issues that they could be experiencing in making payments/refunds. I have spent so much money already on phone calls and still the money is not in my bank account. No one can tell me when my money will be paid back till now. The fact is I am not interested in stories now, I just want my money back in my bank account URGENTLY.
