Terrible customer service from Spec-Savers

Honestly terrible service from Spec-Savers Musgrave. Received a call on Saturday that my glasses were ready for me to collect. Unfortunately, as I had hurt my foot, I had asked my dad to collect them for me. When I received the glasses, I was given the wrong frame as well as the wrong prescription. Basically, I was given a wrong pair of glasses entirely. When I called, they stated that it's definitely the wrong pair and I should bring it back and they will then give me the correct pair. Baring in mind I'm injured, I made my way back to Musgrave center to exchange the glasses. Without any apologies for the confusion and the extra trip, the glasses were taken away. After about a 10 minute wait, I was told that my glasses had not arrived, therefore they would not be able to give me anything as yet. I was informed that they will contact the lab and then let me know when I can collect my glasses. Seriously? Not the service I am used of from spec-savers, as this is not my first time using the spec-savers company (have been to other branches). If this is the service level, then I'd rather not use them at all.
