I’ve just returned from a wasted trip care of these guys
Well, I don't know your specifics, but I do know it usually takes two to tango, and I also know that one is much more likely to hear from those with negative things to say, whatever the cause, than those who have had good experiences.
Personally, I completed my PPL at FIS in 18 days, theory and all, and everyone was courteous (including Hans, which is a lot to say for a German

) and professional. According to my logbook I flew 8:45 hours in the first four days, and 12:45 in the first week; I don't think it would have been very advisable to cram a lot of hours in the beginning anyway.
Point is, I still made it in under three weeks and importantly, without sacrificing standards, so not quite sure why you were flapping about your perceived lack of flying--then again, as I've said I don't know your personal circumstances. While I took the time I took because I though that was all that was needed and there was no point in fucking about for half a year if it could be done in less, I would have been perfectly happy anyway if it had turned out my assessment was wrong, or circumstances hadn't allowed that kind of pace.
I'm not saying that was your case, but if you happened to come across as an overdemanding "I'm the customer" type then I imagine they might be less inclined to help. They did not guarantee that you could do a so-called intensive PPL back then and I have no reason to believe they do now, although of course I'm sure they'll be happy for you to try if you wish.
I cannot vouch for them from recent experience, but I recognise they do offer a rather unique and attractive proposal: UK-quality training in Southern Spain-quality weather. You also have the bonus of flying from proper airports and in proper airspace. Certainly the 3000m of tarmac in Seville helped a lot with my first landings

I'm kind of surprised there aren't more outfits like that in Europe.
