Worst Service Ever

Worst service ever from an optometrist. From all the staff that I interacted with the only person that was pleasant to talk to was a lady names Sarah and even though I had a terrible experience from the beginning I went back because of her friendliness and professionalism. So this is my story. I had an appointment on the 20 May at 12:30 but had to reschedule so on whatsapp I rescheduled to the 21 May at 09:00, got a confirmation on whatsapp which I still have on my phone. I go to Spec-savers Karaglen on the 21st May the ladies at reception had no booking for me, I showed them the whatsapp. Sarah advised that there was no time availability until 10:15 and the optician was also not in and was only going to be in at 09:30 and she already has an appointment but the other lady just kept on asking me to complete the medical aid detail form...how am I supposed to complete my medical details without an appointment and I even asked her this and she said she will see if the 09:30 appointment does not show up and I asked her what if the person does show up. So I left but thought let me see if I can make the appointment at 10:15 and Karaglen is the closes to fetch the spectacles as well. Did the eye test at 10:15 with the most unfriendly person, her questions were more of an interrogation than anything. I could not choose a frame because I had something urgent that I needed to do. On the 25th May I went back to choose a frame and the lady at reception showed my couple frames and then told me to go on the website and I can choose 6 frames and there is a bigger variety compared to what they have in the store and it will be delivered to my home etc. I ask her whether the site also had the size of the frames because I have a very small face and even a small is big on face so I went through the ones on the site and could not find much as per price and variety as well as I was worried about the size so I went back on the 28 May and chose a frame to be told I need to come back at anytime when the optician is there so that she can do measurements for the multifocal lens. So I called on the 31 May before I could go in to find out if it was ok come in at 10:30 as the lady that answered the phone was talking to me she told me she had to leave and will call back and the cut the call so I called back and a very rude lady names Faisa (I might have got her name incorrect-apologies) told me there was an emergency and will call be back and I was about to ask her if they got my details and I also had an emergency so therefore I called back but this lady was so rude and abrupt that she told me if I did not understand what is an emergency so I cut the call as I could hear it was an emergency. There is no need to be rude no matter the situation! If it was such an urgent situation why did she even answer the phone! She did call back and I apologised for calling and insisting assistance as I can understand that the person was priority but this last incident just made me change my mind where I asked the lady to send me my script and I will get my frame elsewehere...never ever did I experience service like this and never ever will I go back to Spec-savers Karaglen
