Website is good but I don't like the time-out feature. I had to go to find my bank card and I timed out somInhad to go through the whole order again, and ended up missing the mattress from the original order at great expense.

RTG’s reply:

Thank you for your feedback. We will certainly speak to our digital team about the time-out and the loss of session. Thank you for placing an order with RTG.
The service was excellent until the point of delivery. Delivery date was arranged, however the driver did not turn up with the bed and mattress and did not inform anyone he would not be delivering on the agreed date.
the driver when he did deliver was alone, the bed was so heavy he was not able to lift alone, luckily there was a man available to help unload. however this was not expected to be the case, so not sure how the bed would have been delivered if this had not been the case.

RTG’s reply:

Thank you for taking the time to comment. To enable us to despatch our products on an express delivery within 2-3 days we use the services of a third party doorstep carrier company. We are very sorry to hear that you had a negative experience with the delivery of your bed and will pass on your feedback to the carrier company involved. We are currently investigating additional delivery options including a 2 man room of choice service which we hope to add to our delivery options in the near future.
