Horrendous customer service, unnecessary fees and a huge let down

1. On the veiwing of the flat myself and my friend had to take holiday leave at work as they wouldn't agree to an evening or weekend viewing. On the morning of the veiwing the agent said the locks had been changed over night and she had the wrong key so we couldn't view it. 2. Was told the flat would be available in two weeks to move in, however we didn't hear anything for over a month and when I tried calling (and got ignored while the guy on the phone wished his colleagues a great weekend) that they didn't know what was going on and didn't own the property yet. 3. We then got asked for extausionate fees which were also unnecessary such as an immigration check (although we both have UK passports) a charge for the inventory check list and check in fee (as well as a very pricey admin fee amongst other charges). I also requested a list of furniture but didn't receive one along with a second viewing which didn't happen. 4. Exactly 1 week before the move in at approx 5pm on a Friday before the bank holiday and after we had paid the fees, we got an email to say the application had been withdrawn by the landlord - I asked why and they said due to personal circumstances. We were left without anywhere to go and didn't get offered alternative options or any kind of back-up/or to even say we would be prioritised for any new properties. Absolutely dreadful experience and wouldn't wish it on anyone.
