Mum left me 6 bags of mini eggs to distribute to her grandkids. Mums away

Each bag also had a fiver in it.
Posted two at my brothers for his lads, sorted.
Posted tow at my sisters for her lads, sorted.
Purposely drove through a certain village Tuesday on my way back on the school run and posted two for my kids.
Sent the daughter a text an hour later.
'Have you got your Easter goodies, fiver from gran, and a fiver from me and Margaret'.
Here's the rest of the conversation.
Hello, I can't text back cos I don't have credit. I wondered when you were coming cos ash asked. Xx
I've been duck. Shoved them through the letter box.
Oh right, we can't see them. Put them in the right letter box. ? Haha
I kin hope not !!
They really aren't here haha, even my boyfriend looked.
Well someone's had 2 bags of mini eggs and £20 !!
Nice....
Google street view tells me I got the right house. There aren't half some theiving B**** in ****** {P
Nah cos if it was through the letter box, no one could get it, plus Ashley would have heard it. He has been in all day and so has mum. Well I've told nana cos I thought she should know that the money she sent hasn't got here.

So if someone could kindly explain WTF
