I meant it in an open ended way - its possible someone might have contract law on their side but they may or may not bother chasing it up. It wasn't meant in an "ignore it at your own peril" kind of way more you might choose to ignore it hoping for the best.
I was just curious. I have first hand experience of something similar happening, with both Parcel Force and UPS. They both threatened police action, but this was because they actually couldn't do anything about the situation.
A brief overview of the situations were:
Parcelforce:
I refused to pay their handling fee, and I argued them into submission over their right to actually hold my parcel. They eventually handed it over, I offered to reimburse them only for the VAT. They stated that they accept all or nothing. So I opted got nothing and took my parcel anyway.
UPS:
I had 2 guitars and 2 bass guitars delivered from America. The driver allowed me to open and inspect them all before realising that there were fees attached. I expected fees, but these were well in excess of what they were supposed to be.
The seller had also sent some concerning messages after they were dispatched.
The UPS guy wanted me to package them all up and give them back. I politely refused and referenced the concerning message the seller sent (it was along the lines of how they aren't willing to take responsibility for any issues even if it's their own fault).
Anyway, I politely refused, they guy called head office and I had a talk with them. Again I refused to package them back up and stated that they weren't leaving.
A week or so later, I got a knock on the door from the UPS collections department from like 40 miles away.
He wanted the guitars back, and threatened police action again. He even dropped this great line "we're friendly with the police around here, so they do favours for us."
He wasn't particularly pleased when I told him that I'm aware of how the police work, and that I know they're aren't gonna get involved with a civil matter.
I was actually on the door step with the guy for an hour rejecting every way he rephrased "can you box the guitars up and give them to us?" He told a few lies to try and get me to go along with him. Mainly claiming that they were legally their property, it was theft and whatever other variation he could think up.
Anyway, after an hour he realised he wasn't getting what he wanted, he decided to go. But the most bizarre part is that he thanked me for being civil, as he isn't used to having to pay a visit to someone who doesn't just kick off and shout. He said he'd be back, I haven't heard anything from them in about 2 years I think?
Anyway, the point I'm making is that I think both of those situations would warrant a stronger response than the OP's, and yet they did nothing. So I hight highly doubt that they're going to do anything at all to the OP beyond sending some letters with false claims on it.
