Have done all that without suffering any sense of guilt ?
A couple of times I contacted the companies to let them know their notices did not reach the right person. No reply or acknowledgement.
Both sides are bad. Not my problem. My problem is people using my email and creating trash in my inbox.
Every time this sort of thing happens I make my best effort to inform all the parties involved, and block the senders as a last resort.
Be a better netizen.
