Disappointed with the quality of my Ray-Ban glasses

On the 04 March 2018 my husband purchased a Ray-Ban glasses as a birthday gift for me. 3 days late, I had it on my head as I sneezed it fell of and the lens cracked. I insisted that Ray-Ban get it fixed as the lens are not fully covered by the frame of the glasses making the glasses even more fragile. Which they did. In December 2018 the glasses slipped from my hand and the lens cracked AGAIN. My husband was so fed up with the glasses cracking he reused to get it fixed as it would cost R1500 and he already spent R3000 'something' for the glasses.2 days ago I lifted the glasses to put it on and the temple literally fell on my lap. Its not even a year that I have the glasses and I have experienced endless problems with the quality. I'm extremely disappointed as we paid a lot for it.
