Using relevant information from the scenario below, write a concise opening paragraph only of an email where you are requesting a full refund for a hair dryer still under warranty.

Recently $($July $20)$ I purchased a hair dryer, the TurboDri $2000($for $49\mathrm{.}95$ plus tax of $$3\mathrm{.}43).$ I work at salon called MillionHairs, and I use this hair dryer professionally. It stopped working right in the middle of my heaviest day, and I$\text{'}$m pretty ticked off. It's a heavy$-$duty model, and I used it only five days. When I returned it to CostCo $($Peachtree Blvd$.,$ Quebec City$))$ and said I wanted my money back, I was told I had to write to you.
