Unwanted marketing is a crime by the law but one can opt out of it by filing a petition or a request in court. Only some firms are exempted from this law. To avoid unwanted marketing one can file a request in the court to be in the list of numbers which are not to be called by telemarketing firms.

I personally think that one should not barge into somebody’s private space causing any form of inconvenience to the end user. Telemarketing should be handled more responsibly to avoid such situations and maintain standards of marketing and not degrade them.
