2 months later,still no refund,bad communication & poor service

We rented a car for the weekend of 1st September,returned it on the 4th.As per the agreement,paid the deposit of R2000.A week or 2 later after no further communication from Thrifty I called in to check when I would be refunded.I was sent pillar to post as the company alleged that we have exceeded our chosen mileages of 100kms a day according to their records.However,I brought it to their attention that we had ordered 400kms a day & sent them proof.After that I have been send around between their Sandton branch & head office with no help.It has been 2 months & still have not received my money.I have wasted money already trying to get this issue solved.Some of the people are rude & overall their customer service is poor.They don't communicate & always wait for you to chase them.I am tired with this company & will never use their services.How hard can it be to refund a client if they have done everything according to the agreement?Two months later they are still makin
