PATHETIC

Could someone please explain to me how can my voucher be used online even though i dont even have an online profile. I went to the store to purchase a product and pay with my voucher i was told to resolve my issue it would take a WHOLE WEEK AS THE PERSON IS WORKING FROM HOME AND WILL ONLY SEE THE COMPLAIN A DAY LATER CAUSE OF NETWORK ISSUES. NO EMPATHY WHAT SO EVER I HAVE NEVER BEEN SO ILL TREATED BY A MANAGER AND TELLER. NO VALID REASON WAS PROVIDED AS TO HOW MY GIFT VOUCHER WAS PURCHASED WITHOUT MY CONSENT HOW ON EARTH DOES THAT HAPPEN.
