Time wasters, no people s****s, cannot calm a irate customer

I called the canal walk store on the 26th July 5 times and the line got dropped finally after the 6th attempt and trying for a hour I got threw to store and I told them i was not able to reach them where I was told the people in the store was busy. WOW......... OK so i get put threw to kids clothing where I asked for 2 specific items of clothing a red boys puffer jacket 13-14 and a boy blue leather jacket 13-14 and repated myself thrice as I wanted to exchange my current items and asked to keep it aside as I will come to store later in the day that was just after 1pm but before 2pm. I get to store 15:03pm to wait in a line that I am in alone with 1 cashier open helping the person infront of me. I get to the till ask for my items then they bring out the leather jacket but the red puffer jacket is the incorrect jacket instead of a boys item its a girls puffer jacket. the cashier then walks out behind the till to go look for the right jacket withoout telling me I go look too because time is being wasted, I then ask for the manager who then is not helpful at all. I was frustrated as the time was going and I had to get back to work and i was trying to avoid hold up thats why I called earlier already so it would of been a simple exchange. the manager had no people s****s and not apologetic at all. the manager then pulls off the tag from the jacket saying they will keep it and try to find one for me when asked will that affect anything as the tag is off the item I was told no, as that was a major concern to me. I want the red BOYS puffer 13-14 brought to canal walk store so i can collect it, i formal apology for the inconveince and a voucher to use at your store for my time wasted.
