Terrible Ethics and Business Practice

Europcar has the worst service ever!

I took a trip to Durban and hired a car from Europcar, Paid the deposit of R2 000.00 . I was informed that they will return my deposit after the trip with deductions made for any damages or fuel used(Which I understand is standard business practice for car hire) .

The deposit was returned with the deductions I agreed were correct. Few weeks down the line, they start sending me SMS's and their lawyers calling me saying I owe some money. I explained to the lawyers that if there was money due to Europecars it should have been withdrawn from the deposit. They have now threatened to take legal action for this amount, till to date I do not know what the amount is for and I do not expect them to be demanding the money where-else it should have been withdrawn from MY deposit.

I don't understand how they do business, as I have previously used other rental cars but Europcar is the absolute worst and is the pits!!!!
