Bad bad service

I went for a eye test and new glasses were needed. When I got the glasses I could see about 3 meters ahead of me which has never happened in the 30 years. I went back and eyes were re tested and a slight difference were detected. It was re done but the result still the same. I was then asked by them (spec savers Brackenfell) to try and get use to them. I told them since I am on the road 12 hours per day it is impossible for me to try and get use to glasses which I can only see 3 meters far with and after my vision became very blurry. An accident waiting to happen. I then demanded my money to be paid back to the medical aid in order for me to go to another service provider and after a long fight they agreed to do so. I then paid the consultation fee. They confirmed on 2 August that they will refund it. I keep on sending her emails to find out when the money will be paid back because until today nothing reflects on my medical record. She does not even respond to my emails. Yesterday I requested the medical aid to call them while I was on the phone. Afterwards they called me back saying that they could not get hold of the person who is dealing with it. Twice they **** about me collecting the glasses whilst it was still in their shop. I really need this money to be paid back ASAP since I need new glasses and need the money to pay for that, cannot afford to pay it out of my pocket
