Poor service - Spec-Savers Vaal Mall

I have had a most terrible experience with Spec-Savers in Vaal Mall. I had dropped of my daughters glasses to be fitted with a new frame on the 20th August. They informed me that it would take a week to get it fitted. I call back after a week as I did not hear from them, only for them to tell me they would call me back in 10 minutes because they had too many customers in store to help!!! An hour later I am still waiting for a call, so I call them back. they then inform me that the glasses are not ready, and it will only be ready the following week. I explained them that they told me it would take a week, to which they then now informed me they meant "7 working days". Someone from the store called me on the 29th Aug to say it will be ready the following day. Two days later I still haven't received a call to come fetch the glasses, so I call them and they tell me that their lab "****" to them and the glasses are not ready like they promised. It has been 11 days and my daughter who has poor eyesight is going to school without glasses. It has been a struggle, and no one at the Spec-Savers seems to be able to do anything or they seem unconcerned, only offering the apologies! This is such poor service and my family has been regular customers over the years! This is very disappointing, I would not recommend their business at all.
