I have rented Easement Heathrow Airport a few times and had good cars and good service. But... Following a rental they will send you link to review, and for doing so they will provide you with a promotional offer - like £5 off your next rental or free extra diver etc. I had a long term rental so the extra driver offer was very attractive and would have saved me over £270. I got to the desk outside normal hours and the lone guy there was unable to deal with this offer - after making several phone calls etc. Having just come off a long-haul flight, spending 40 mins at a rental desk was the last thing that I wanted! Eventually I was asked to pay for the extra driver and ring customer services during office hours to claim a refund. I rang and the customer services and the rep. said that to get the refund I would need to send them a copy of the offer e-mail, survey and survey confirmation (even though I presented all of this at the rental desk). I did what was asked, however over 4 months later and 6 e-mails and 2 calls still no refund. To renege on an offer is dishonesty in my book, however, it is the scant regard to customer service after the event that this company exhibits that has really rilled me. My last e-mail to Customer Services was the 20th June 17 - no one responds! Pick this company on displayed price only - forget about their offers.
