Billed twice for the same car d

I was incorrectly sent a damage claim post car rental return. Upon calling they investigated and advised they were incorrect, and I would be credited. I was credited, but then a week later the money was again taken from my account. I had to investigate again, and they again were at fault. To this day the money inst yet refunded, and my consistent request for a call from management with an apology has been ignored. <br> <br> I am incurring consistent use of my own time and funds to sort out the *********** billing.<br> I would like compensation for this.
