Rude, patronizing & bad service

I went for an eye check up for spectacles and contact lens. They told me that my distance lenses aha changed. I agreed that I will change my lenses for the new ones and paid for the charge. They told me it’ll take two weeks. As my contact lens have also changed, they told me they’ll give some samples for me to try. When I asked for it in the shop, they said they didn’t have any and they would post it to my home address. They never did. Today I went to the shop and was passed to the manager. He asked me to try the glasses and I pointed out that I’ve my old contacts in and couldn’t really see the difference. However the glasses did t fit on the bridge of my nose - he just squeeze the bridge support together. When I asked for the contact lens, I was told to make a new appointment- which I refused. Things got a bit heisted and then I was told not to swear which I hadn’t - practically calling me a liar. He was so patronizing and it seems all his defense was to say I swore at him I DID NOT! He told me to come back tomorrow for the new contact lens - almost dismissing me in his pathetic patronizing way. Is this what Vision Express is about and how they have managers to abuse customers? He should never be in a position where contact with the public is made.
