Arrived and went into the building to drop off car keys. Building was filled with cigarette smoke, man was very abrupt and no welcome or greeting. Dropped us off at free car park section by Shelter and told us to wait there for our return trip after phoning them on arrival back into Airport. On our return did exactly as instructed- called them at 12.10am, they said they were on their way to collect us. Still waiting to be picked up at 12.40am! (It's a 5 min journey for them). Rang them again and had a very rude man on phone - asking me "well where are you waiting". I replied "where you told me to wait when I was dropped off the other day". "I never dropped you off love" was his reply. My plane had landed an hour ago by this time and it was very cold to be outside for that length of time. Would not recommend at all. Very disorganised and a severe lack of customer care. Major training and improvements needed. Had used previously 7 years ago and had a great experience then (when depot was on Speke Boulevard). Gone seriously downhill since then unfortunately. Will not be using again 😥.
