Unsatisfied service

Spec Savers at rustenburg Square. I was there on the 17/01 for an eye test for glasses cause I've been receiving severe headaches only to find out that my eyes are the problem. I recieved a confirmation sms stating that I can track my order to see when it's done and ready for collection, on the tracking website it told me that my glasses will be ready between the 26-29th of January. I contacted spec savers and they informed me no the parcel tracking is incorrect it is at dispatch on the 7th of Feb it will be ready for collection by the 10rd I re-visted the branch on the 11th and they informed me no it's at dispatch it will be ready by the 14th. So today is the 14th and I contacted spec savers this morning at 08:00 in terms of my glasses they told me it's there, the optometrist should just validate and sign off the glasses. I called now again at 13:45 and they told me that my lenses are incorrect they need to replace my order and I'll be able to get my glasses by the end of the week. I am extremely unhappy with the service as I keep on getting redirected and postponed to another day, this is unacceptable especially towards the clients that are really struggling without prescription glasses.
