REFUSAL ON A REFUND OF A PRODUCT BOUGHT AT CLICKS

I BOUGHT A CLICKS MANUAL BREAST PUMP IN JULY AT CLICKS AND I NOTICED THAT IT IS WRITTEN ON THE PACKAGE THAT IF THE CUSTOMER IS UNSATISFIED CLICKS WILL GLADLY GIVE A FULL REFUND.SO I WENT HOME AND TRIED THE PRODUCT AND I WAS NOT SATISFIED,THE WAS NO MILK COMING OUT NOT EVEN A SINGLE AMOUNT OF MILK CAME OUT.BUT THE MILK CAME OUT AS I WAS USING MY HANDS SO I DECIDED TO GO ASK FOR REFUND AS I WAS COMPLETELY SATISFIED WITH THIS PRODUCT.I WENT TO CLICKS AND EXPLAINED TO THE MANAGER WHAT MY PROBLEM IS,THE MANAGER WAS VERY RUDE,COLD AND UNWELCOMING.HE RESPONDED TO ME IN A VERY RUDE WAY IN FRONT OF OTHER CUTOMERS.SO I NOTICED THAT AS I WAS TELLING HIM MY PROBLEM HE WAS JUST SORTING OUT A PROBLEM OF SOMEBODY WHO STOLE SOME EARINGS AND RAN AWAY.SO HE WAS ACTUALLY OFFLOADING ALL THAT ANGER ON ME AND THAT IS TOTALLY UNACCEPTABLE.I WENT OUT OF THE SHOP VERY SAD I EVEN FELT LIKE CRYING BECAUSE I WAS TREATED LIKE A PIECE OF *******.SO I TRIED TO CALL THE CUSTOMER CARE AND STILL I DID NOT GET ANY HELP.I AM STILL STUCK WITH THE PRODUCT I HAVE SPEND MONEY ON AND AM NOT HAPPY ABOUT.THE ONLY PERSON WHO GOT SATISFIED IS CLICKS BECAUSE THEY GOT THE MONEY.
