What is the difference between Consumer and a Customer? P.S - It is not the one who buys is a customer and one who consumes is a consumer

Good attempt brother, but it is not at all confusing. Its a very easy definition.

Waiting for more responses

The terms "consumer" and "customer" are often used interchangeably, but a consumer and customer are not always the same entity. In essence, consumers use products while customers buy them. A consumer may also be a customer and a customer can also be a consumer, but situations occur where this is not the case. In general, your marketing efforts should be geared toward the consumer, rather than the customer.
