Bad and Embarrassing Service

I bought a bicycle @ Game Store in Centurion Mall for my son on Wednesday eve on a display bcz all the technicians knocked off @ 18:00. Thursday the handle was loose, I couldn't take it back bcz I ws going to arrive @ the same time as the previous day, so I decided to take it back Sat morn, instead of an apology to my surprise I was in an embarrassing argument with staff members of sports dept bcz I asked for new one, as that one was damaged. I was told about the tires, yet no one checked them when we bought it. After all of that drama I got it. Late today its Sunday, we discovered that it is also not connected properly, the chains are loose the brakes are too tight, my son is frustrated because he is sitting with bicycle that he cannot ride, now I hv to take a day off to take it back again, what is not making sense to me is, how come ppl from the same dept can knock off at once? leaving the dept empty, who is supposed to assist customer on that last hour? my worse frustration is to go back to those ppl who treated me so bad & ask them to fix the same bicycle, I want my money so I can go & buy it somewhere I will be valued & treated with respect & fairly as I am spending my
