Called in RGB 3-4 weeks ago now. Spoke to the lad behind the counter and he agreed to order in a sigma 10-20mm for me and ring me when it arrived. I rang them today to ask if it had arrived. They had no record of my order and said they wern't getting any 3.5f lenses in. Told them I was not happy and wouldn't shop with them again. What a let down and a waste of my time. Lesson learnt. will pay a bit more at Jessops for guaranteed customer service.
