Pep and their useless reading glasses

2 weeks ago I bought some reading glasses from PEP for R80.a week later the *****s of the glasses fall out and it was a big job repairing it.so I bought another pair of glasses.so I waited till the *****s of the first glasses falls out again before using the second pair of glasses.then I found it missed a lens.unusable.so now I must keep on repairing the first glasses from *****s that keeps falling out.the first glasses was R80 and the second was R60.daylight ******* if you ask me
