Ridicualting Other Customers

I write this letter in great disgust and hopefully the last time i visit this store, i have been a loyal customer to musica since 2010 buying cds and games, I went to Musica on the 02 May 2015 at around 14:30pm, i have found out from the guy that works with me that there is a special on bluethooth ear pieces, so i went to the shop and spoke directly to the manager to assist, she told me that there was a guy that came in earlier to place an order as well, so i asked if she can help, and then i left, on Saturday 16 May 2015, the guy that works with me recieves a phone call to tell him that his bluethooth device is here, I phoned the store at around 13:00pm and asked the Manager how come i did not recieve mine as well, she told me the guy came a day before that is very untrue, When i dropped the call, she tells my working collegue that i am rude, this morning 18 May 2015 at around 07:00am this guy asks me why i was so rude, she does not know me and how to deal with customers, I dont want musicas unproffessionalim coming to my work place, i am the customer, i donot owe musica anything to bring me up in front of other customers, this matter should be treated with the highest interest
