All, hi. Hi. For a very long time I've been in company. From the very bottom of my childhood, I began about 15-20 years ago and now I have a rich fortune behind me. Now I need to redesign a little in the internet era and in particular my customer service, because what we are doing now are just errors. My best friend told me to order a service in this branch. This salesforce license cost over $300 for my big company, but I think it is not too costly to get it.
