Siegel and Yacht discuss two steps that need to be done after your purchase. The first of these is maintenance, to ensure that you maintain the item you have purchased and that it does not have any problems. A vacuum cleaner requires basic maintenance and cleaning to ensure it functions properly. Maintenance can be difficult if you don't understand, with a car this maintenance can be much more difficult to perform. The last of course is how to respond to dissatisfaction, this can be difficult depending on the company you are buying from. My job as a customer service supervisor for a cable company gives me a good understanding of this topic. Ideally, in most situations you will want to work with the company you are purchasing the item from to resolve any issues, but in some situations you may need to opt for alternatives such as contacting the best company.
