Questionable marketing practice

I read a news report about the following marketing practice:

* the bank sends a letter to offer you a credit line
* if you do not want it, you have to tell the bank
* if you do not opt out, the bank offers it to you
* the charge is waived for the first year
* in subsequent years, the bank automatically add the charge to your account
* it is quite a hassle to remove this unwanted facility

I hope that the authority can act strongly to stop this practice. Here are some of the difficulties faced by the consumer:

* the product brochure sent by the bank is complicated (not easy for consumer to understand)
* the terms may be unfair to the consumer (as it is written on a one-sided basis)
* the consumer may overlook the charge on this statement (for something that is not needed).

I hope that businesses can be runned ethically to serve consumers, and not to make profit at the expense of consumers.
