repair after repair and still have broken glasses

At the end of January, I had an accident, and the one arm of my glasses broke. After being shuffled from store to store, finally someone at Spec savers decided to assist me, almost 2 weeks without my glasses I get it back with a new hinge. a week later the other side of my glasses break, which wasnt a problem before. They take it away for a week and i get it back....superglued!!!!! After this I was over it, I cant go any longer without my glasses. Yesterday I put them on, and the first hinge that was 'repaired' is now broken again. I do not throw my glasses around, I take care of my stuff, but judging on how I was originally treated by Spec Savers (2 different stores) I dont think they actually repaired it properly, and have every excuse under the sun. I now have to take MORE time out of my day to get this sorted, and who knows how long they will keep my glasses now!!!! Im sick of this! It puts too much strain on my eyes, which is not healthy. can you not sort this out once and for all now? Or have I wasted my hard earned money getting glasses through Spec Savers?
