Specsavers bad sevice

I went to specsavers Bethal branch and was told my glasses would be ready in 2 weeks, it was not. Upon receiving them i explained that i can not see proberly and was told to wear them for 7 days so that my eyes can adjust. This did not happen, i went back and was re tested and told the left lens was not correct. They re ordered, i waited 10 days and went to find out if they lens have arrived, i was told they are at a lab in witbank. The branch sent to the lab and i was told they wil be back friday, did not happen i was told they will be back Monday, also did not happen. Then it would be back Wednesday... Gues what? It did not happen. Throughout this i am the one suffering with headaches and irritated eyes. I was told the Courier was to blame but while in store on Wednesday they arrived and my glasses were not in the box which the lab said was dispatched on friday. My advice... Stay away from specsavers as not even specsavers H q bothers to reply on my complaint
