The customer services team will ensure that the customer has his/her goods delivered to where they want, and when they want them.
After buying some products consumers would expect to be able to receive after-sales service. For example: when buying a computer you will be given a guarantee that protects its parts for a year and you will be given a helpline telephone number; when you shop at Sainsbury you can ask for somebody to pack your shopping and then carry the bags to your car.
Some businesses provide free after-sales service, but others may charge you for it. Extended guarantees on electrical equipment are often very expensive and some helpline telephone numbers will charge you premium rates for calling them.
