In that case you do not really know what customer service means.

Customer services means a company providing services to a customer or potential customer. It includes pre-sales services (employees who can answer a cutomer's questions) and any after sales services. It also does not just refer to a specific person but the entity as a whole. For example a company where you can only communicate by letter has poor customer services. One that allows emails is less bad but still bad. One that you can only communicate to by phone is okay on that level. One that you can go to store and they are willing to help and they know what they are doing have good customer services.

For example, I said I did not want another Nokia device because of poor customer services. It took almost two months for Nokia to provide me a replacement N900 when the usb port died. That is very very bad customer services.

Customer services is not just a guy on a phone. It is the entity as a whole and the services it provides to the public.
