Unprofessional service from Spec Savers Centurion Mall

I went to Spec Savers in Centurion Mall around 4 weeks ago, for my eye test and prescription spectacles. The test went well, I selected my frame and then that’s where the problem came in. They wanted to claim from my medical aid savings account and I told them they mustn’t do that coz I still had credit available with Fever tree, of which they gave me that information, and also loyalty points. I then asked them to claim the difference from my medical savings. I was informed that they would send me the invoice via email the next day. Nothing was sent so the following day I went to the branch and still, I was informed that the invoice would be sent to me. It’s been a month now and I haven’t heard anything from them. I’m disappointed in the service and I had already chose a frame for the specs and the shades so I dono if they still put them away or they sent them back to the shelves. I’m a loyal customer of Spec Savers but I have not had such terrible service. It’s unprofessional and I will make sure that I spread the message for people not to go to any Spec Savers coz the service is terrible.
