Fantastic Services review: End of tenancy and move in cleanings

The worst company I have ever done business with. After paying their membership fee (only to learn that credits could be applied just once to each 'kind' of service--read the small print, if you can find it!) we contracted for move in and end-of-tenancy cleanings. (See what the company promises on their webpage.) The 'team' that arrived to clean our four-story house was a couple, who showed up with a hoover, bucket and some mops. Amongst other problems, none of the high areas (tops of light and shower fixtures, picture rails, window shades, etc.) got dusted because the cleaners did not bring a ladder. (The 'checklist' entailed the taller of the couple following me around with a rag to give an extra swipe wherever I pointed out dust or dirt.) We had to accept an £80 refund (on £670 move-in cleaning fee, plus £89 for the membership--note that every extra space, no matter the size, gets totted up according to a standard rate, so the base cleaning rate can grow exponentially) as we needed to move in the day after cleaning, meaning we could not take advantage of the "free re-clean" offer. For our end of tenancy cleaning, the same couple showed up: they did not do the windows because they did not have the right equipment. Worse, they did no more than pass a mop over kitchen and bathroom floors that needed deep cleaning. (The excuse was that they did not want to 'damage' the floors! I later spent three hours cleaning the floors myself, with before and after photos to prove it. This alone should have merited a full refund of the fee. Instead, photos I showed the company were dismissed as 'damage.') I also have many photos of areas that were left uncleaned (corners of window frames, stains on cabinets, walls and shelves, dirty door sills, etc.) The cleaners left without sticking around for me to sign off on the checklist; they also left the flat unlocked and threw their dirty sponges in our recycling bin. All of this resulted in a very unhappy landlord and extra charges to us. Repeated complaints yielded small refunds (customer service staff when I could get them on the line were friendly and helpful but obviously limited in what they could offer by company policy). Their "best and final" offer was a "30% refund" on the end of tenancy cleaning (£50, on £161) with a 72 hour window for accepting. I was so insulted at the time that I could not accept it. Correspondence on the claim totals almost 3,000 words, so it was a huge waste of time too. Eventually Fantastic Services stopped returning my calls and, in the end, they still got more than £800 of our money for decidedly less than fantastic service. (Given their poor service, I wonder how much of this money the cleaners actually received.) Avoid.
