We paid the $200 pre-authorisation fee almost a month ago. On their website it says you need to wait 10 days before it's deposited back into your account.
After 3 weeks we contacted them and they informed us they would deposit the money back into our account.
We contacted them again today and was informed we needed to "speak with our bank" because gowithgecko no longer had our money and it was the "banks responsibility".
If you're going to use this hire place I would probably kiss goodbye to any deposits you place. :).
