Feedback
Overall a good service. I would recommend it to others and use it again. Website is clear and easy to follow, the different part number was clearly shown as the correct replacement for what I needed. The part availability request was answered promptly the request for a suitable fitter took a little longer but was still OK. Delivery time was reasonable, but it did arrive one day early good, but would have been annoying if Id made special arrangements for accepting the delivery. My only criticism is of the confirmation emails. Some were sent in duplicate, which would have been confusing if Id had several different items on order. And one confirmation of despatch arrived after the part had been delivered and fitted!
...John Weddell
I am absolutely delighted with both the helpfulness of your operator, who called back with availability of stock and delivery when I needed them urgently and quality of the shower hand grips. They arrived when promised. My only suggestion would be for you to supply the screws with the item but I suppose this would increase the price which was very competitive. Many thanks.
...Patsy Hooper
My Tub deliveried the seat when they said. They also sent me an email re the dimensions of the seat l had ordered as there are 2 seats which are similar, which was a nice touch. No complaints.
...Brendan Noctor
Excellent service and communication. Ordered a regulator for Stoves oven which was obsolete, My Tub contacted Stoves for replacement part information. It was cheaper than original item. We searched around the net to find fitting instructions, so less than £25, much cheaper than the £900 we feared! Would highly recommend and definitely use again, thank you!
...J Nixon
I was kept informed of progress throughout the order process, even when my order had not come in as expected you told me then a week later you told me my order was dispatched. The item is exactly what i wanted and is now fitted and working perfectly well. You were the best value for money and I would use you again.
...W J Griffiths
The availability and the price of this product was second to none. Sadly the delivery service to the pick up depot was not to such a high standard as this very fragile part arrived in a less than adequate envelope broken despite being marked fragile. This was quickly replaced by you and was carefully looked after at the depot. An extra quid or so on better packaging would be better to speed delivery and reduce returns.
...Christopher Collins
Great service and good price. Thanks.
...paul maguire
Fast delivery thank you.
...Shirley stacey
Good service and good communication from start to finish. I have to admit that I was sceptical that the company would refund the delivery charge if I collected the item myself from a nearby plumbing supplier. But they did on the day I picked it up. So am very pleased with the service and highly recommend MyTub.
...Ged Mead
Good customer support. Item delivered as per your instructions. Thank you.
