terrible attitude and defective product

i purchased a bicycle from makro woodmead on 01/11/2015. the frame of the bicycle was bent and on 12/12/15 i went in to makro crown mines to get it replaced. the lady on duty brenda asked me to wait for the sports person to inspect it.they tell me that it is beyond 7 days and they will have to book the bicycle in lebogang makhine says if im not happy with that i can go to woodmead and see if theyll help me. i asked for the manager and kidebone mabe was called. she had a bigger attitude than lebogang and besides not being helpful i was treated with utter disrespect. now i dont deserve to be treated this way and they both casually strolled away and did absolutely nothing. i had to book the bicycle in and its more than a month and i have had no response. clearly the staff and management are not clued up with cpa laws regarding defective goods and i have raised the issue with consumer watch so to let others know how makro works.i expect an apology from the staff as if thats the way makro encourages staff to treat customers then i will never enter another makro again.
