I booked Enigma Airport Parking Ltd on line via MOBIT Airport parking (ezybook.co.uk) web comparison site. On departure we were kept waiting 20 minutes at the drop off point, even though I called them 30 minutes prior to arrival at the drop off point, as instructed. Upon our return I phoned and was told my car would be with me within half an hour. Half an hour later I called again only to be told that I was booked for a 5pm return, when in-fact my booking form said 1:45pm. I was again told my car was on its way. 20 minutes later I called again and was told I was calling the wrong company. I explained I was calling the number on my booking form. I was then asked what time, when and where I had dropped the car off and to describe the person I had given my car key to. I was also asked to describe what my car key looked like. After listening to them argue amongst themselves I was told again that I wasn't supposed to be arriving until 5pm. I told them they were mistaken and sent them a copy, via text, of my booking form. Approximately 20 minutes later I received a call telling me to make my way from the agreed collection point on level 4, to the drop off point outside terminal 3. I was given my key but was not given the ticket to pay for parking, so I was completely unaware that I was supposed to pay the parking at this location, as it was different to the drop off point where the driver collecting my car did give me a ticket to pay the charge. To cap it I received a parking charge notice of £40 from APCOA Parking which I have paid to avoid being charged £80. I have emailed both Enigma and Mobit Airport parking (ezybook.co.uk) several times and they have not bothered to reply.
