6. On February 1, Ann sends Bob a letter offering to employ Bob at Ann’s auto dealership. On February 5, Bob mails Ann a letter accepting the offer. On February 6, Ann has a change of heart and calls Bob to revoke the offer. On February 7, Ann receives Bob’s acceptance. Was a contract ever formed? If so, when? If not, why not?

A Contract was formed on February 5th

Explanation:

The contract was formed the very day that Bob mailed Ann his acceptance which was on the 5th of February.

Ann attempted to revoke the acceptance too late as she did it a day after he had emailed his acceptance even though she only received it on the 7th.

The date she received the acceptance is of no consequence because this falls under the Posting Rule. This rule in Common Law countries essentially states an agreement is made as soon as the letter is posted even if it never gets to it's destination.

A company's customer service department interacts with customers after they have purchased the product.

Explanation:

Customer service is the provision of customer service before, during and after the purchase of a product or service.  It consists of a sequence of actions aimed at increasing the level of customer satisfaction - that is, the formation of the client's feeling that the product or service meets his expectations.

 It is useful for a company to analyze customer service requests to learn how the product can be improved, but also how to generate additional revenue from accessories, etc.
