Conclusion:
I think OP is trying to delay the payment
This part is clear.
and the loan that has been received by someone else is nothing but gossip which has been made to get sympathy for what can take a long time to repay the loan.
Maybe. Maybe not. Either way, this is pure speculation. And don't forget: all of this could have been prevented if you would have asked for a signed message to begin with.
That being said, OP volunteered to pay back the debt and made a promise:
I will repay Shashan but not on the designated date given to the loan; every time I receive a payment in a Signature Campaign/another source of income, I will deposit this immediately to Shashan's Address as repayment for the trouble created by that hacker.
I know doesn't having a job makes me suffer with this debt, I just changed my wallet address in signature campaign for a while to cater to my expenses, and based on our conversation I will send the payment this coming week. As you can see I keep updating you once I send the funds
To use a movie quote: "
Rule One: Never change the deal",
especially not without discussing it first.
Note: I will create a scam accusation if I do not get positive response from the OP.
Interesting case.
