Hey Jordan,

Just wanted to drop u a line to say thanx for making my purchase an enjoyable experience. The advice you gave me was invaluable and is much appreciated.

As someone who is in the customer service industry, I am all too often familiar with the negative feedback given to phone sales agents but Jordan you are very diligent and know you product line extensively. It is fun and refreshing to speak to someone who is upbeat and very tech savvy rather than someone who is dull and unaware of the products they are dealing in.

I will most assuredly be placing future orders with CompSource not only because you have unbeatable prices but also because you have unbeatable customer service. You are an asset to your company and hope you will share this with your superiors.

Sincerely

Thomas F Anonymous
