Igate — incorrect power of spectacles made by igate kaggadasapura

Igate optics kaggadasapura talked me into buying expensive power glasses. Upon receiving, it was found that igate optics made spectacles which are 1no of power (In both bifocal) lesser than what was mentioned on doctors prescription. When approached, they refused to exchange or change the number/power of glasses. Extremely uncomfortable spectacles made. Been 9 months, retailer refused to change glasses or to refund the money. Highly irresponsible. Disappointing services by igate kagadaspura. Regret buying. Need my money back. Igate have cheated me. Pack of fraudsters. Pls never go to them.
