Pathetic service

I visited vision works Woodmead on Sunday to do an eye test since my contact lenses began to hurt and I could not see clearly with them anymore. I mentioned to the man at reception as well as the optometrist that I saw the adverti*****t for the R90 special on eye tests and I would just like to get tested to get new contact lenses. After completing the eye test, I get told that I owe R350 instead of the R90 which I initially mentioned. All I was told is “sorry we didn’t tell you, but a contact lense eye test is always more than a glasses eye test”. The service and attitude received was absolutely pathetic. I then paid the R350 for the test and asked how much the contact lenses would cost. The optometrist said that if I order it on the same day as my eye test, I will receive a discount on the lenses and also confirmed the amount with me R540 less 20%. I proceeded to order the lenses and told her I would make a payment on collection. The man at reception confidently told me he would give me a call as soon as the lenses are ready, and this would have been by the Friday. I waited the entire week with no call. The following Sunday, I called the Woodmead branch to query when my contact lenses would be available to collect. Very confidently, the man at reception advised me that it was already there, awaiting my collection-no phonecall was made the entire week and he did not have anything to say when I mentioned that. As I got to the branch to collect and pay for my contact lenses, he first said I do not have to pay because he put it through my medical aid. I had to tell him that I have to pay cash because my medical aid would not fund for it. He then stated that I have to pay R540. I asked why would I have to pay the full amount when I was told about the discount (which was the only reason I proceeded to order the lenses after receiving such pathetic service) He disappeared into the office for a few seconds then came back to tell me that I would only get the discount if I ordered a 6 month supply , it would not apply for the 3 month supply of lenses. Now that I started using the contact lenses, i am unable to see far as everything is blurry. All the optometrist did was the glasses screen test, put on a pair of contact lenses and make me check if the floor seems tilted or normal, not even do the screen test with the lenses on. Following the worst optometrist experience EVER, can I even contact the branch and advise of my problem? Will I even receive any sort of assistance? I would definitely discourage anybody from going to vision works Woodmead after my experience. R 890 gone down the drain. An absolute waste of time and money.
