Very bad experience! I have bought a mattress on 29th September that has to be delivered on 1st october (a "next day delivery" or "chosen date delivery"). I wasted all the day to wait for this mattress. Next day the customer care (30 min at phone waiting for an answer) only told me that I would receive a phone call from the carrier the week later (the week later??? what about the "next day date delivery"???)... I wrote them on the form in the website to have some help. They answered me only 7 days later (during which the mattress has not arrived, and nobody has called me). I answered to this email proposing for a new date on monday 12th october. The answer of this email was on 12th (?!?!?) proposing me another date: "Wednesday the 15th" (wednesday of that week was the 14th!!!! They are also unable to look at the calendar). Then I answered that for me was ok to be delivered for "wednesday the 14th", but unfortunately the customer care person meaned "Thursday the 15th" on his email... I finally proposed for another day, monday the 19th (because we can't stay at home again on the day they had proposed) trying to be gentle and pointing out that for a "next day delivery" people can usually organize it for the day after (that was 14th). In this final proposal I write them to be sure about the delivery, and I was reassured about that. What do you think? That I had finally received the mattress on monday 19th????? No... another day waiting uselessly.... And my back pain is increasing... It was a very waste of time for me and my girlfriend too!!! We can't wait all these days off to wait for a mattress!!! Conclusion: More than 20 days for a "next day delivery" are an impossible thing to think about, for a web site that is deemed among the best e-commerce in the UK. Be sure that I will never buy anything from WoldStore and its affiliates websites!!!!!
