Frustrating and *********** customer service

I app**** for a virtual number and it took them 1 full week to give me the telephone number. They claim the number has been activated but when I dial the number it says the number does not exist. I have tried calling their support and every time they transfer me to another department. All the consultants that I have spoken to have no clue what a virtual number is. Why sell a product if you don't know what you are selling? I am so frustrated because no matter what number I call, I am not receiving any assistants.
