Bought a hot tub in may only used it a couple of times and by june it started smoking bad and blew up. I kept ringing customer service and couldnt get through,sent loads of emails and still no reply. Complained to the range as thats where i bought it from and they arranged for clever spa to ring me. Said they would arrange for hot tub to be picked up........now in september and today is the day its finally (suppose to be) getting collected,fingers crossed it does. God knows how long its gonna take for a refund though
