I ordered four TRV's and required a next day delivery, which I paid for and had qualified to get. They should have been delivered before 6.30pm next day. I had hoped not to be the last delivery of the day but waited patiently. The tracking system said it was on board, so I waited at the job hoping it was just late. It did not turn up till the day after that and It was only luck that someone was in to receive them. I reported the incident to you and was told I would be refunded "the difference" (Which has not happened yet). I am disgusted that I paid for a delivery service that I did not get I.E. "Next day service" and have to pay at all for it. To be offered "The difference" is an insult and unjust. Don't advertise "Next day service" if you can't deliver it. I appreciate this is contracted out. I hope they are suitably dealt with, but as it is you who has been paid, you get the complaint. The products (TRV's) are fine and I have no complaint with them at all. Shame about the delivery service.
