Failure to open on notice time

I am deeply disappointed in Mr Price at Fleurdal Mall. A written notice was issued and pasted on their windows that they will open at 4 pm on the 6 of October 2015 due to stock taking. After waiting for more than 2 hours they failed to open the store for shoppers. I confronted one of the staff members who simply laughed at me. I than spoke to the manager who could not give me a clear answer saying there was an error in their system and that they will simply open on the 7 October. Thus the manager was ********* and not trustworthy tarnishing the image of the store. I will never trust anything that Mr Price say!!!
