Game delivering poor service..AGAIN

I registered a complaint on the 10/02/2015 about a sunbeam fan that was on promo at Game and there was no stock when I went the day after the promo started, I was then contacted by Susan from Game Midrand who told me that they will not be getting stock of this fan but will arrange a more expensive fan at the same price of the promo fan. She then told me she will keep the fan aside for me, I told her I will collect it on Sunday, Due to an emergency I could not go and fetch it on Sunday, I then called numerous times on Monday and for the rest of the week but the call was not going through, I tried other branches and their calls went through, Today I finally get through only to be told by Susan that I didn't come collect it so they sold it. I explained that I tried calling and she advised me there was a problem with their lines,HOW IS THIS MY PROBLEM AS A CLIENT?i made the efforts to call, no1 from the store contacted me to even ask if im still coming for it. today the store manager calls with a \don't care attitude"all he could say was \""I cannot get you a fan\"" for a store to be part of such a large group (mass cash) I must say this is shocking service"
