US Mail Sales Ad, promo mailer, new customer promo, US Mail Hughes promotion flyer

I have recently received, my 3rd item in the US Mail. This invitation for a new customer, this sales and marketing ad, this promo - due to being on a mailing list, is not welcome. The idea that I am a current HughesNet customer, and, received items sent via US Mail in 2023, caused me to call corporate office. I managed to get a reprieve-from July 2023 to March 2024. The sales and marketing department, or, the contract company/contract vendor used for mass marketing 'mailer' items, are being cute, being underhanded - this person or department added a letter A to the mailing address. The residence I occupy, does not have multiple structures, does not have a space A, space B space C - different example, a main hose, a house A, a house B, so on. Why annoy an existing customer with an unwanted, not needed, sales flyer, sales advert, sales pitch,mailer promo? Why remove the actual home address from a mailing list, to then add a 'house A ,a space A? where do I mail these back to? No, not simply ignore, not simply throw away-- the address needs to be removed from the mailing list,address needs to be removed from existence.
