Cant think of a title

Hi had booked a eye test at spec savers Promenade on Tue 27 Mar 2018 and after completing my test went to choose a new frame but could not find a frame that I liked the person assisting me said that they are waiting on their new styles of frames to arrive and that I could choose a frame at a later stage and that I need not choose a frame that day I then asked the assistant that if I chose a frame at a later date would I then still qualify for the special that was running at the time which was a free set of sunglasses from a frame I could choose depending on the price of the frame I chose for my glasses and confirmed that yes I could. I then waited on them to contact me to say the new frames has arrived but after more than a week I went to spec savers online store and found a frame that I liked and called the assistant and asked him to get that frame after I provided him with the frame code found on the spec savers website after another long wait I was finally able to test fit the frame I had chosen on the 16/04/2018 so now its time to choose my free frame for the sunglasses and as my new frame alone came to R2000 I would have qualified for a frame at the max value of R1490 which I think is the frames with the green stickers but no now I can only choose frames with in a lower price range and the free frame no longer applies if I choose a frame in the price range they specify I can then have that frame for R690 cash and they will then make sunglassed from them for me. At this point I will admit to being rude to the assistant I said that he was f@king me over and to f888 off, told him just to finish my prescription glasses and nothing else he then has the nerve to tell me that it may take up to a month to arrive and I said Ive been waiting almost a month just for a frame already so I am used to waiting so what diffrence does it make. Not only is this spec savers level of service **** poor they are ***** as well
