Online shopping nightmare

I made an online purchase, had to wait 5 working days and they deliver the wrong item. Incorrect color,grey instead of black. Why I'm upset that no on one is taking ownership of the mistake,just for a courtesy call I have to wait 48 hours. Shops response ma'am if you not happy get a refund because they having endless problems with the on-line shopping. If so they must upgrade or quality check the items before. Close the online site because tomorrow my son will be the only child without a black shirt. Service is not worth a star to be honest My online reference number ********** 52
