Lucky Gam - Bedford Centre - ******* and Rude

Hello All going to make a long story short, purchased a cable (phone cable) and they said it cost 350, it was fairly nice, but i did ask is it really that much for these and are they certain, and they said yes its the going rate etc, so purchased and got back home, and a friend let me know, look online, they cost at most 150, so i phoned them and let them know, then the attitude is rude and why dont we just go online etc, and they dont display prices but thumb suck , and now refuse to take the item back , essentially they shall overcharge and rip you off and have no worries, and for a place such as bedford centre you'd expect more
