Bad Service experience- Deposit payment

What a bad experience I've had with AVIS care rentals. Its 18 days later since i have returned the car and they haven't paid my deposit back.

I spoke to the supervisor on the 11th day since return and she said they have done a manual payment and it should take about 72 hours, they will communicate with the bank to check if they have received the manual instruction. She was promised to call me 2 days after to check but 8 days later no one from AVIS has called and i have not received my deposit.

Their Slogan is Customer's first which it means, we are here to ensure the satisfactory of our customers. I am very disappointed because the terms and conditions i have signed clearly said my deposit will be paid 10 days after i returned the car. If there was any damage to the car, Avis will not even bother but take my money as they please because it is favorable to them. In this case it me running after them.

I will never use them again.
