Query: TUBES BLEW UP

I SENT A EMAIL TO THE COMPANY AS MY TUBES ALL EXPANDED TO AN EXPLOSIVE SIZE AND WHEN I OPENED ONE OF THE TUBES I ORDERED THE BUBBLING LIQUID CAME SHUTTING OUT. WHEN I PUT IT IN MY WHITENING TRAY IT BURNED MY TONGUE. I HAVE USED THIS PRODUCT BEFORE WITH GOOD RESULTS, ALTHOUGH I HAD WHITENED FROM A GEL THAT I ORDERED THROUGH MY DENTIST. I HAD USED THIS GEL FOR RETOUCHING. I AM VERY DISSAPOINTED AND ADVISE IF YOU GET TUBES THAT SWELL UP AND IMPLODE ON OPENING WITH LIQUID BUBBING INSTEAD OF A CLEAR GEL THAT YOU PLEASE DON'T USE IT AND SEND IT BACK!!!!!!
