Cbeyond is possibly the most annoying telco/ISP company I have run across.
They go through sales reps and move them around frequently... each time having them cold call, solicit, and generally annoy me and my customers.
I have to worry about the extremely pushy and aggressive sales tactics. Some may say that this is good business. But I will never give them my or my customer's business.
Interestingly enough, most of their sales people are young and attractive... seemingly new to the job market and eager to sell, sell, sell... or more like happy to have a job.
Before being "convinced", "sold", or bullied into buying their products/services, I recommend that you do some research. Or better yet, choose another vendor.
