While in some cases, companies have sent postal mail to the investor that their payment could not be processed, in other cases, the investors are not receiving any intimation about the non-payment of the refund or interest or dividend.
Most people are discarding all the investment and payment papers they receive, so it is difficult for them to trace the amount due.
Only a few like the domain investor are retaining all the papers, and they find that many payments are still not processed, the investor will have to visit offices or send a large number of letters to the companies where they have invested since emails are not being delivered.
