CPAP office, Do they train any of you on professionalism or customer service? Because, I've never felt so belittled. You tell me to call before I come down, because I may not actually need to, but then I can't get anyone to answer the phone when I do. So, I go down to find out what is wrong with my machine, and I explain the problem as best as I can, only to be humiliated by Debra. How about instead of making your patients feel stupid, you educate them? I'm sorry I'm not an expert in your field.
