This 8 digit number is not a typo. It is a collection agency based in India with a US office in Buffalo, NY. They will continue to call you after you make it clear to them that they have the wrong number. It is extremely hard to hear what they are saying with their strong Indian accents so it makes it hard to get your number off their lists.
Some of the calls were from Kumar, Alita Fernaces, and Brobal. The spelling of all these names is questionable. Their bosses are Nick and A.J. but they are never available, as they are either not there or in the bathroom. When they might be in the bathroom, Brobal is unable to check and see because he claims he is not allowed to go to the bathroom.
