Waiting for my glasses for over 5 weeks

I went for an eye-test on the 23 January 2022 and I was told it would take 2/3 weeks to get have my glasses ready for collection. I have not received any call, sms or email feedback about the specs until I called today 03 March 2022 to enquire about my glasses. I was told they have been sitting there ready for collection. I'm travelling to JHB today and I'm not sure when I'll return, I need my glasses. The shop is only +/- 40kms away from my place of employment but they have refused to organise a delivery. I'm really upset about the service and that nobody tried to contact me to inform me to collect. I paid my hard earned money at their shop and would like to have this sorted out. I fly out at 17:00.
