Extremely unpleasant service received at Specsavers Vaal Mall

I had the worst experience with Specsavers Vaal Mall, from extremely rude to staff to order not being processed whereas the claim was made to the medical aid. I went into the branch on the 28 of January for eye test and a new pair of spectacles, the admin helping with opening the lucky the Optometrist who helped me on the day was not bad and very friendly. After the Eye test i choose a frame and ordered a pair of spectacles. I wanted to order contact lenses but due to insufficient funds on the medical aid i could not order. When i was ordering the spectacles i forgot to add thinning on the lens. Few days after the branch visit i called in asking them to cancel my spectacles order and add thinning. The lady i spoke to was again very rude and told me that she will cancel the order but i have to go to the store for a new quote. Of which i did not course by then i had decided i am going to use someone else. About two weeks after the eye test i received a call from the branch to come and collect my contact lens which i did not order. Trial contact lens was for me. I asked my husband to fetch the contact lens for me when he arrived at the branch, he was told that there is no such order and he left. Few minutes after he left, they called me again asking him to go back they found the contact lens and he could not go back. On the same day the lady told me they are still waiting for the order of my spectacle which they are expecting the following week. This was a surprise as the order was cancelled according to me, when i asked if the order was not cancelled, she told me it was not cancelled and confirmed that thinning was added to the lens. On the 9 of March i went to the store to collect the contact lens order and enquire about spectacles. Still the same story it took the staff almost 30 minutes looking for the contact lens only to find that it was trials which i did not ask for. When i asked about status of the spectacles i was shocked to be told that the spectacles were never ordered at the same time the Specsavers claimed from the medical aid and the claim was approved meaning i cannot make spectacles anywhere else. I asked them to cancel the order and process the credit note back to the medical aid, today when i called to find why a month later, did they still not process the credit note i was told it was never done and nobody knew why. I am sitting here 2-3 months later without spectacles and no funds on my medical aid to do another pair of spectacles.
