In tv advertisement they were told about tablets which increase height and i noticed their number and contacted they gave us guareenty .is this right?

Right vs. Wrong: People sell all sorts of things... So hang on tightly to your wallet! a healthy person will grow the same amount with or without growth pills sold on tv or sold anywhere else. So, if a person is still growing, he will be guaranteed to grow while taking growth pills. He will also be guaranteed to grow the exact same amount without the growth pills (but he'll have more money left in his wallet).

Ignore: Sounds like this scheme is designed to increase the height of the pile of money the sellers are accumulating. I don't know of any pill that will increase height. If you are concerned about your growth, please have a discussion with your doctor about it. Hope this helps.
