I'm not happy with the service I get. I want to return my glasses and go elsewhere

Got glasses at Dynamic Vision at Keywest Mall in krugersdorp and I'm really not happy with it. The first pair I got was fine then a ***** fell out and they fixed it, not even a week goes by suddenly the frame breaks. I took it back and they said that it's a factory fault okay I accept it and the issue me a new frame but a plastic frame. I liked the frame but now the glasses are loose mind you I got this new frame on the 25th of May on a Monday after receiving the call on the same day. When I took my glasses in they had no scratches on the lens but when I received them they had a bad scratch on my right lens. The lady siting behind the desk says she can't help me because she's not the one that helps. Every time I come there they keep saying they can't help I should wait for the lady that helped me which is never there

I'm starting to get irritated with these glasses coz it left a sore on my ear and it hurts they said I should come today before 1 I went the at 12 and I was told to come back tomorrow. I don't want these glasses I don't want anything from Dynamic vision because I'm really ****ed now 😡 if I can be refunded for my glasses I'd take it because they keep making me run up and down only to get no help. I can write a book on my experience with them but that's just a waste of my time. Can somebody please help with this problem
