You need to take care of a couple of things here:
The classnames of the <span> looks dynamic and and may change sooner or later, even may be next time you access the application afresh.
Selenium doesn't permit compund class names
Solution
To identify the element you can use the following locator strategies:
Using FindElementByCss:
bot.FindElementByCss("span[title='Customer']")
Using FindElementByXPath:
bot.FindElementByXPath("//span[#title='Customer' and text()='Customer']")
