Unhappiness with service received

I dropped off a few pairs of shoes to have heel tips replaced on Saturday. the gentleman I was dealing with was helpful. I indicated I would collect on sunday, I was unable to and Monday on my way from work I called, the lady answered said they were closed but I should come Tuesday at 8am when they open. I arrived and the shop was closed. I waited for 40minutes before they came. I opted to wait as I was leaving for cpt and needed the shoes. I was waiting with the guy who fixed my shoes as he didn't have a key to the shop. when Maureen finally arrived I went in with the shoe guy and quickly got my shoes and paid him and then started to rush out as I was late. at the door Maureen blocks me from exiting and says wheres your slip, which the shoe guy had, she then demands to know if I paid, I thought this was very rude as I had never dealt with her, and how can I leave the shop without paying. I was very disturbed by this and the fact that they only rocked up 40 minutes after the time, and no one apologised instead she mumbled something about the bus. very unprofessional, very rude, and they clearly don't trust the guy who does the shoes. BRAND FAIL
