Underhand practice at collection counter. I collected my car key at Malaga airport and due to being in a hurry for a mtg did not question the additional €175 charge on the contract (fuel etc). Upon returning the car with a full tank I received just €82, when I questioned this with customer service they said €29 for airport tax (fair enough I thought) and €64 for a vehicle upgrade that I was not told of not was it needed as I was travelling on my own. The Malaga counter staff are pushing the hard sell for insurance, breakdown etc. but to put in a charge without mention is a new low. I raised with the Customer Service team who said that as if signed I had to pay the upgrade. Beware everyone and take a minute to check what you are paying for, some really unscrupulous counter staff at Malaga Goldcar counter.
