Titan Eye Plus — about my spectacles that I purchased from titan eye plus

Address:

Mangaldeep building , hill cart road, Darjeeling, West Bengal

I am having very high astigmatism. At the time of purchasing from titan eye plus they didn't tell me that the frame i chose will not accommodate such high power glasses. Due to this there is alignment issue that i can't even wear the spectacle, using my old one, then what will i do this to this new spectacle, what is fault, i paid such a huge amount
