Ordered Oppo large truss on fitting it was wrong size for me .Telephoned to ask if I could exchange for a medium and was told that is fine. Returned truss by signed for 1st class post on Saturday which you received on Monday. Phoned on Wednesday for update assured it had been sent on Tuesday and would be with me by Friday/Saturday did not arrive. Phoned on the Monday and told it must be lost in the post. Requested a refund which was done immediately. No truss ever arrived obviously never sent. Ordered from Amazon received next day £1 more expensive shoud have purchased there in the first place
