Okay, you say her communication has been poor.

I strongly doubt she is a solicitor.

As for the strange message you received, I am wondering if that was predictive text kicking in. With that, if you don't double check, you can get some weird words substituted in your messages, I have had it happen to me. I don't know what it was you sold, but that message the second time suggests to me she had decided it wasn't worth the hassles of pick up and had told you you could keep it.

I guess I am going to go against the trend here. I personally would send another message. I would say I still had the (whatever it is) at my home awaiting collection & it needed to be collected within the next 30 days or after that, weekly storage fees would need to be charged, could she please let you know asap about collection.

See what happens and take it from there.
