Ordered a top of the range roomba. Delivery was delayed by two days whilst they tried to contact me by phone to pressure me into paying for an extended warranty (which i had already turned down at point of purchase). When it did arrive, they had sent a far inferior model, nearly £200 cheaper. Tried getting through to customer services, kept on hold for ages, then when I explained the problem, they put me on hold for another 15 mins, then the line went dead. Rang back and been on hold for another 30 mins. Wish I'd done my research before buying from these con artists.
