The goblin lead Harry to a conference room, where he sat until he was joined by the Goblin 'Griphook' and the meeting went exactly as Harry had planned. First he impressed him with his politeness and respectful attitude before confirming he was Harry Potter through a blood test, he then feigned shock at finding out he had more than one vault at all, and told Griphook how he only found out about that one through a letter from his mother.
"Your magical guardian should have told you about the Potter vault, I didn't expect him to know about the others but you should at least know about the Potter one. I mean, he's been taking money from it for seven years so he could pay for your living expenses."
"He what?!" Harry's shock was genuine this time "that's bull! Pardon my rudeness but I don't even know who my magical guardian is, I've lived with muggles my whole life and they'd never spend money on me if they could help it. Only on themselves or my precious cousin, they beat and starve me and make me live in a cupboard for merlin's sake!"
"They what?!" Griphook mirrored Harry's previous reaction except with a bit more rage "how dare they?! Even goblins treat children with love and respect! Your muggle family, they're known as the Dursley's right? Well it appears that they have been given a large sum of money from your account every month, the equivalent of £500 a month. This money was given because they were supposed to look after you, but they clearly haven't."
"Could you stop them from receiving this money?"
"Even better" Griphook smiled "we can force them to repay it all"
"Yes!" Harry nearly jumped with joy "please do that, the look on their faces would be priceless. But while I have your attention, who is my magical guardian?"
"Albus Dumbledore is not your legal magical guardian, but he did claim guardianship of your in Gringotts eyes. Your true guardian had become, shall we say 'unavailable' and Dumbledore claimed the role from a Gringotts point of view. In case this is unclear, he's not your guardian but the bank thought of him as such your parents will was sealed. No doubt by him. However if you wish, we can remove him from the role and force him to return any money he took from your account. But I should let you know that if we do so then it returns to your actual magical guardian, Sirius black"
Harry agreed and talked with Griphook about Sirius, finding out he had a godfather who apparently betrayed his parents but was never given a trial was quite interesting. Harry soon after took some money from his trust vault, and visited his family vault. He found a letter from his parents, telling him how they loved him, the prophecy and how he should be careful with Dumbledore. Things he already knew, but it also told him about how Sirius Black wasn't the secret keeper and Dumbledore knew about it. Merlin told him how he didn't know everything but he was hoping this was one of the things he did.
He thanked Griphook, leaving him a bag of galleons from his own vault as a thank you and reason to keep quiet about him coming here. He had exchanged some galleons into pounds so he could go shopping for muggle clothes before spending galleons at a nice ice cream shop he found and buying a seven compartment trunk where each compartment was the size of a room. He made sure it had a library, bedroom, toilet/bathroom, kitchen, potions room, dueling chamber and a swimming pool. He also paid extra to make sure only he could open it. He spent the rest of his time wandering around, and he was enjoying himself when suddenly he was tackled by a red blur.
