Bad service

I am very disappointed with the service I received from Spec-Savers Olivedale. I ordered my glasses on 10 June 2020 they said i should come back after 7-10 working days. On the 10th day I didn't receive a call to say the glasses are there, so on the 11th day i went to check on the order, the glasses were there but they didn't have anti-glare so they had to send them back and after that I went to the branch a few times to check if the glasses were there. On Monday 6 July 2020 I went to check on the glasses and they were still not there I even tried demanding for a refund but they said they I will receive my order soon. On Thursday 9 July 2020 I went again to check on the order and my glasses were still not there and they said i will receive them on the following day which is the Friday 10 July 2020. Today it's the 11th of July 2020 its been a month and 1 day and I have not received my glasses yet. I am extremely frustrated and I wish I could get my money back.
