Interpreting the word yes

[Christmaspyjamas]

I reached out to a professional contact to ask for a small favour on text.

Contact replied immediately with the single word yes.

I replied thanking them then sent an email with some details they needed.

One week later no reply.

Chased by email politely.

No reply.

The favour would have taken around 10 minutes and is fairly urgent (clear from the context).

Should I assume the yes is actually a no?

I find this pretty rude and whilst they didn't have to say yes, having done so and then not followed through I feel a bit awkward around the person.

On my phone, when I read a text, it comes up with an automatic reply I can click on. Maybe this person has the same and accidently clicked "yes" without meaning to

The only way to know for sure is to ask them. Maybe they intend to help but don't realise it's an urgent matter.
You need to find out for sure though so send another message asking clearly (but politely) if the person is still able to grant the favour. Make sure you state the urgency of it.

Also, I noticed you initially asked through a text message but then followed it up with emails. Do you think perhaps they haven't regularly checked the emails and maybe missed your follow ups?
I would message again as I previously said but through text rather than email. Hopefully you'll get some response.

This could have happened...

Oh @WrendaleCountryDogs I think you're right.

The reason I say that is because the response was immediate when actually I would have thought agreeing to the favour would have involved some thought and possibly a bit of clarification.

Also this person normally takes a good couple of hours to respond to messages....

I suspect they never meant to say yes.....but might find it a bit awkward to explain that.

I'm not keen on chasing this person as they're very senior and don't respond well to chasing.

Stupid autoreplies!!
