Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry at the way the automated assistant may have offended you. I hope that I can do better.
As for a wrong remote, that is definitely a matter for mailing back the item, to the company that you bought the remote from. That company is undoubtedly not my company, I'm glad to say... I work for JustAnswer.com, which is not a shipping company nor a mail-order nor an internet-order company, and thus could not possibly in any event have sent you a wrong remote.
I hope I can provide some helpful advice, but the above are the basics of the case for sure. I do not know of the company that you bought the remote from, but if you tell me I can give you further instructions. Also, a thought: if going to the post office is inconvenient for you (it certainly is, for me! beyond any doubts, so I agree on that point...) then I wonder if you could use UPS Ground delivery instead, having it picked up at your door? For a slight extra charge perhaps... and if the company that sent you the remote is so cheap as to only have a P. O. Box address to return it to, that of course would not be an option.
But, it would mean you would just have to pack up the wrong remote in its original packaging, seal it up, and put a label on it with the return address of the company that sent it to you on the label. And then call United Parcel Service (UPS) for a UPS Ground pickup.
For a few extra dollars (since UPS is not government-funded the way the US Postal Service is) but for the convenience of not having to go to the post office, I hope that would do.
Let me know what you think - and if you need help on any point. Especially, the name of the company or store or vendor that you are returning the remote to. And I will advise you further.
