Lying to a courier company

Q: I have ordered online. The courier delivered the item to the security or maid. I then asked the sender where is my items as it was not delivered to me and the proof of delivery has the maid or security name. They then offered a refund or replacement. I did this a few times with a few companies. I wanted to know if this is haraam

Selling a stolen phone

Q: I bought a phone to sell from someone but when they came to sell it while I'm paying them they say the phone is on contract and they have a way of wiping the name of the person who took the contract off from the database etc. so they don't have to pay etc.

Afterwards I realized it's like stolen so I messaged the person and told him I want to return it but he's now insisting that the contract will be paid for monthly.

What do I do? I sold the phone now, what do I do with the money from it? Is it halal for me to use or must give it away in charity?
