Missing spare wheel when handing the vehicle back

We hired a vehicle with Hertz Rent A Car for one week during March. When we arrived on the 23rd March, the gentleman who helped us didn't want to the vehicle, so we called him back to do so, but still did not do a proper job, so my wife and I had to make him walk around the vehicle to check for scratches etc. This was a rushed job.<br> <br> When we spoke to the lady at the help desk, we said that we has problems with not receiving deposits back from the Rental car companies, so she assure us we'd get our money back unless there was an accident or with conditions mentioned in the contract. I found that the deposit was absolutely rediculously high. I paid on my credit card and she assured us that we would get the money back.<br> <br> On handing in the car, another gentleman found the spare wheel was missing. We got such a shock, because there was no break-in during this time & and the car always locked. The gentleman who assisted us in checking in the vehicle on return, said that he knew that the original man that assisted us was called \Mr. Hertz\". He also said that he never checks cars properly. I haven't received my deposit back &amp
