Having had a few rentals now from these people and provided feedback, which to their credit they have actually called me to thank and take action about, my last time will certainly be the last time. Starting off with the booking, they have now got a new "lucky dip" option, this is to get their staff commission (nice of them). On booking confirmation it actually tells you which car type you've been given, mine was a Saloon. However for the customer. this is not the case. You arrive at the pick up and told "so you've gone for a lucky dip and it seems you've got the basic" so low and behold you've got a crappy 3 wheeler now. But wait, I can give you an upgrade, with "my special discount" and upgrade you to an Audi/BMW or Merc!! Adding an extra 50%!! to your rental. Huh?? The sell begins, come and have a look, sit in it, rev the engine, others in the room join in "I've got one of those cars (I'm sure you do) and trust me, smooth bla bla". So FYI, DO NOT PAY THE EXTRA FOR THE LUCKY DIP!! The additional documents is also a puzzler, you really need to read the small print on your booking. There were a few "huh" customers when asked for proof of address. On top of that there is the still existing forced sell of additional insurance...surprised they don't include life insurance, Sky Subscriptions, Mobile phone contracts. "Drop the excess and pay an extra 25% on your booking, otherwise, you're liable for the premium excess of £1000!!! and that will basically end your life in financial turmoil". The never ending list of things you will be liable for begins. When you say no, the smile on their faces disappears and "let's get this idiot out of here tone" comes in. Upon finally getting to the car, the checks were not done and it turned out the car was low on oil. So another was given, one that wasn't cleaned. Forbid you should give someone another car and even if it is an upgrade, at least they get a clean one. Coffee stains in console, outside had just gathered dust, inside even had a empty drinks bottle. After 45mins, i really couldn't be bothered anymore. The fact that I had to go back into the office to ask "do you not need to change the reg details" (and they did), I think it was apparent even they were happy to see this failed commission leave the court. Also ensure you get in early, their process is never ending, took me 45mins to get my car and drive out. On the positive note, the team are really polite and welcoming, so you've done that right. Advice for Sixt, give your staff better salaries so they don't need to affect your bottom line with this approach. Bottom line being returning customers!
