SPEC-Savers Cavendish Poor service

Recent dealings with Spec-Savers Cavendish Claremont Cape Town pathetic poor service. Returned with faulty pair of spectacles. Lenses cut too big for frame causing lenses to pop out of frame. Spec-saver proceeded to replace with new lenses, cut and fitted to old frame. Due to original lenses been too big, this stretched frame. Second attempt new frame chosen and we were informed new lenses would be cut and fitted to new frame. Multiple trips, telephone calls Spec-savers full of excuses and not honouring the agreement.
