Marketing of personal loans by banks

I received two calls on my mobile phone for marketing people of the banks selling their personal loans. I told them that they are not allowed to call my mobile phone for their marketing of their products. It is terrible that the marketing people can disturb the public in this manner. Don't we have some ethics and respect for people's privacy? I don't know why our banks now behave in this despicable manner, and why the authority stand by and allow these type of practices to continue without restraint.

NOTE
I receive marketing information by e-mail regularly I do not object to this mode of marketing. I can delete off the materials. But, marketing by mobile phone is objectionable and is an invasion of privacy. I hope that our MPs  know the difference between what is acceptable and what is not and they have time, within the busy schedule and multiple duties, to do their duty as MPs.
