i ordered 2 lots of tubes on 2/10/16 and received one lot on 10/10/16, i rang to ask when the others were going to be delivered and was told would be with me within the week. a week went past no delivery so i rang again to be told they were a stock item but wouldnt give me a delivery date or shipping date. sent numorous emails without any reply, other than one asking if i had had these delivered. i replied no and heard nothing since. i have since had a full refund, though i dont think this is the point. i still need these tubes but i wont be placing any future orders with your company or recommend to friends and family. saying the delivery problems are to do with a new computer system isnt good enough as all orders should have been shipped prior to the system being installed. i still have no idea why you didnt send me the tubes i wanted.
