Young woman asked in a cheerful upbeat voice for Shanmugan Somasundram. I told her he was not at this number, never had been at this number, and is unlikely ever to be at this number, and hung up. My landline number has belonged to me and to my father before me since 1950. My mobile number was issued to me as a brand-new number, never previously assigned, in the early 1990s. Since the beginning of the year I have been getting calls for this apparently very elusive person from various numbers, all related to last-resort collection agencies. I can spell the name of this mysterious person because I once received a text message for him in which the name was spelled out in CAPITAL LETTERS. Here are some of the numbers to watch for: 844-606-1332; 844-610-3970; 902-326-8473; 844-677-6643; 289-850-9939; 780-851-5729. These last-resort collection agencies buy up bad (uncollectable) debt and then try to collect it by using threats and harassment. In fact they are just bumping their gums because the debt is so stale that legal recourse to collect it has expired. But beware: if you once owed such a debt, never ever do anything that might be construed as acknowledgement of it, or it might become legally collectable again. Ignore these parasites and all will be well.
