Round 2 of terrible service from Musgrave Spec-Savers

Round 2 of the same issues with Spec-Savers. I honestly don't know why they bother to contact us to try resolve the issue and ensure that it will not happen again, when it indeed does. After being contacted by Spec-Savers on Monday to apologize for the inconvenience caused, I was contacted and ensured that my glasses would be delivered within the week, before Sunday. I explained to the lady who called me, that I received the sunglasses pair, that I just need my seeing glasses, as I am suffering from headaches. She ensured it would be done as soon as possible. Fast forward to Saturday, I get a call that my glasses are ready and I could collect. I made arrangements to collect on Sunday. Imagine my shock when I get there, and they show me the glasses and its, surprise surprise, sunglasses?? It's now the fourth trip to the mall to actually find that my glasses aren't correct?? Does no one actually check to see what actually needs to be done? Absolutely shocking and I cannot believe this is the service from spec-savers. The consultant at the front desk stated that the glasses would be couriered to me. This worries me as what if it is the wrong glasses again. I will definitely not be using spec-savers again as it seems that no one actually knows what they are supposed to be doing or checking.
