GOODS PAID FOR WOULD NOT CHANGE

MY HUSBAND HAS PURCHASED ME PJ'S AND A GOWN AND SLIPPERS FOR MOTHERS DAY ,I WAS UNFORNATLY ABROAD AND I RECEIVED THE GIFTS ON MY RETURN.IT IS ABOUT 5 MONTHS OLD BUT BRAND NEW UNFORTUATLY THE SIZE IS SMALL AND I WENT TO CHANGE IT AND THEY REFUSE TO JUST EXCHANGR GOODS THAT HAS BEEN PAID FOR ALREADY I DONT WANT THE MONEY BACK I JUST WANT TO EXCHANGE THE PJ'S AND THE GOWN BUT WAS REFUSED AND WAS SHUNT AWAY I WAS VERY UPSET BECAUSE IT IS OUR HARD EARNED MONEY WE PAY FOR WE DO NOT GET THE GOODS FOR FREE , THE GOOD ARE BRAND NEW WITH TAGS ON IN THE SAME PACKET ECT. BUT THEY WIL NOT EXCHANGE IT FOR ME SO ACCORDING TO THEM IT CAN LIE AND COLLECT DUST BUT THEY WILL NOT EXCHANGE THE GOODS , IT WAS A DIFFERENT STORY IF IT WAS UNPAID AND GIVEN FOR FREE TO ME BUT IT IS OUR MONEY AND THEY REFUSE TO JUST EXCHANGE IT TO SATISFY ME AS A CUSTOMER BECUASE. IT WAS BOUGHT AS A GIFT AND IT IS SMALL , SO WHAT DOES THIS TELL US AS CUSTOMERS WE CANNOT EXCHANGE GOODS IF OLDER THAN 6 MONTHS EVEN IF IT IS BRAND NEW STILL AND EVEN IF YOU WERE NOT AVAILABLE TO COME CHANGE IT YOU LOOSE ALL THE WAY AROUND , BESIDES THERE WERE 2 PAIRS SLIPPERS BOUGHT AS WELL I KEPT IT FITS MONEY TO TRUWORTH FOR MAHALA NO EXCHANGE!
