My business partner worked for Sprint for a while and then he worked for Nextel for a bit (which is sprint now). Nextel gives big commissions to salespeople for phone plans and then take the money back away from them if people cancel or stop paying.
They have high pressure management and unreal quotas for most people to meet unless they are real high octane sales.
Anyway, one salesman was ordering plans for companies without their knowledge and having the phones shipped to him at the office and was hiding them in a closet to make quota. He was eventually fired and they didn't know it until someone was looking for something one day and opened the closet and it was full of cell phones. LOL
