They deliberately made it difficult because I didn't purchase additional insurance!

Although I had purchased full insurance from the rental company and prepared a credit card for the deposit, the staff kept pushing their insurance. Even after showing the English version of the contract stating I had full insurance, they refused to acknowledge it. When they tried to process the deposit pre-authorization, they made mistakes and it showed as failed. However, after calling my credit card bank, I confirmed that the first attempt was successful and had an authorization code. The car rental staff refused to verify this, seemingly forcing me to buy their insurance or they would cancel my reservation! It took two hours to finally get the car, greatly affecting my schedule. The pre-authorization occupied £1250 of my credit limit. Appealing this seems like a long wait. Extremely unsatisfactory!

Wait time was longer than all previous car rental companies

The hiring process was so slow and the condition of the hiring company offices is terrible. I had to wait for over an hour to pick up my car. The staff of this company were so rude. The condition of the car was so bad. There was an engine fault on the car and the guy told me to add some liquid to fix it which I did but the fault remained. The car only had quarter of fuel which so inconvenient. I will never book a car with easirent again. Terrible experience overall.

Seems like a good alternative to rental cars.com.

Surprisingly friendly and efficient, but only once at the location, which was a real pain to get to: shuttle bus to nearby off-airport parking runs only 3 times an hour, which is no good if you're in a hurry.
