Have respect for your customers

I upgraded my wifi router last month from a 1 gig to the 20 gig day and 20 gig night. Last night I noticed the 20 gig day was used up. I know i have not used that much data so I log on and see that I was put on the 10 gig plan instead. So I leave work today at 16:30 and get to Westwood mall at 17:30 knowing well that the store closes at 18:00. As I have three contracts with this store. At 17:35 the doors are locked but people are inside as I stand there the last customer is walking out. So I stood there and a black male working for telkom opens the door for the customer to leave. I asked him what time do you close. Hoping to come in earlier the next day to sort the problem out. Without answering properly he starts closing the door on me. Needless to say I lost my cool and ask him again. He responded to say the store closes at 18:00 but because of security it closes at 17:30. There is no signage giving any times what so ever. It took me at hour to get to Westwood mall telkom only to have this rude person close the door on my face. He then continues to say he does like my tone. After he has no respect he expects me to speak to him in a proper manner. He then says he is a man. I rep**** I don't care whether you are a man or not you need to have respect for your customer there is no signage whatsoever to say anything of your times. I am going to publicize this incident as much as I can. Retail staff need to learn that we are customers just because they decided to close 30 minutes earlier does not mean that all the customers know that. Have respect for your customer don't close the door of their face just because you want to go home early. If security is a problem speak to the mall to upgrade their security.
