Order still not received and incorrect information just to close a sale

Blessed day , May you kindly assist me to get my prescription glasses. I went for my eye test 24th December 2023 at Spec-Saver Mall@Reds and was promised will get my glasses after two weeks. On the 27th of Dec I received a sms confirming my order being placed. Two weeks passed without hearing from them and then I decided to call them for a follow up that is when I received a sms from them on the 15th of January 2024 saying my order is ready for collection. I went and only to find that they made my lens for sunglass ,when I raised my concern the lady that assisted me said since it is only the lens that needs to be rectified my frame is okay she then advised that I can take the glasses with they will rectify their mistake and call me after two days which she went at the back to escalate the matter to her manager. On the 16th of January I received a sms confirming my collection meaning I have accepted my glasses, and all is fine. On the 19th Jan I went back for feedback only to find that that lady never escalated the matter, and nothing showed on the system. I then got the 3rd person to assist me ,after I laid a complain she told me that she escalated to her manager and referred me to the initial person that assisted me. After a long wait at the shop it was concluded that I leave my glasses at Mall@Reds on the 19th of Jan 2024 and was promised to get them as soon as they can. On the 2nd of February I called for progress and was told that I must wait for atleast two weeks and when I questioned their service, they said atleast I must give them a week to resolve the matter, which I they guy is telling me that I have to pay R400 and something difference on top of R1399 I paid excluding the medical funds. When I left my glasses I asked if anything is cover so I don't get any surprises when I collect and they guy told me that everything is covered no additional cost. I was told that I need to explain again how I want my lenses meaning three times I was there they never even bother to pay attention to my need as their client.

So it is 7 weeks now still without my glasses ,may you kindly help me voice out my query with Spec-Saver Mall@Reds.
