Once again disgusting service from Europcar

On Sunday my husband returned a vehicle we rented. They inspected the vehicle and told us the deposit will be refunded the next day. Yesterday the money was still not in and I called your cape town international branch which told me it had been invoiced and the money will be in this morning. To date I have not received an invoice. The lady also could not tell me what the refunded deposit amount is. I would like someone who can give me a definate answer as to when the money will be in our account. Things need to get paid and you guys are hanging onto peoples deposits which was pulled off immediately not even just placed on hold. Agreement number is ***.Today is Friday. Still nothing in my account. Please note should my money not reflect by 12 this afternoon I will be letting my attorneys contact u after 12. I'm not going to play with this as things needed to be paid and I will be incurring cost.I have to date also not received an invoice. I just received the deposit amount back which seems incorrect but I have no invoice to see what the charges are.Good day, Please note that this rental was billed incorrectly. We initially took out the car for 7 days with a debit card. We went back every day for 11 days after that to extend it on a daily basis and paid via our debit card for each days extension. Your invoice now shows I was charged for 18 days rental which is wrong as 11 days I have already paid for each and every single day I extended and I'm being billed for this again. This is madness. Another thing is your rate fluctuated so badly that I didnt pay R416 every day of extension. I want my money refunded of the 11 days asap as I will now be forwarding this **************** to my attorney. I'm being double charged for what reason exactly?
