Poor service not to be recommended

I went to spec savers in Cradlestone mall to fix my frames which is still under warranty, I was told that if I take the same frame I don't pay anything but if I take another frame I will be charged an amount of R500+- because the glass have to be cut to fit the new frame in which I told them to keep it as is and get me the same frame, then after 2weeks I went back to hear if my frame arrived yet and it was not there and then I got told that the supplier was closed till the next week. Then a week later I was phoned and the frames is there I told them I cannot just come in I stay on a farm and when I come into town again I'll come in for the frame. A week later after the call I went into town for things I need and stopped and spec savers for the frame everything went well until I needed to get the new frame and was told I need to pay the R500+-, I told them that was not the agreement and the two options that I was given as per above they just look at me and don't know what to do, I told them since that's the case they can put my glass back in the old frame and I'll take my business somewhere else. I see they going to open a ear section there to which i will not be going to I thought that it would be nice and a little closer than my usual place, I go to for my ears but if that is the way you guys is are handling eyes and clients I will not be using it
