The same thing happened to me as it did to you, I have had bad experiences buying some things online, but it was because they did not advise me well, the important thing is to learn and be careful, now that will not happen to us again.

On the other hand, the man who served you knows how to make good sales, customer service is important, and the most important thing is good service, which made the difference. I bet that from now on you will always want him to serve you.=)
