Poor Return policy

I bought a bicycle from a game outlet and Less than three weeks ago and now the bicycle is broken and when a take it back to game eastrand mall for an exchange i am told i must wait for the technician who is busy at Markro to come on friday to check it,and see if he can fix it.

If he cant it will be sent back to the supplier and there is a 21days waiting period i mean i bought the bicycle now cause my son wanted it now,not for him to wait cause game sold me a poor quality product.

I am beyond disgusted
