A&B sold to me an overpriced lens. They sold the SIGMA 70-300mm F4-5.6 DG MACRO Lens to me for HK$ 2500 which I found out to be at around HK$1250 only (around US $210 maximum). I am trying to contact them but to no avail. They manipulated me for being a traveller unfortunately. Could someone give me an advice or help me with this? I really want to have what I paid for and I want my money back!
