Debit orders on days we did not agree on

I bought a bed on credit in June , then went back to the store to make a huge payment then I was left with 2 installments . Fine in July the installment went through as agreed it’s Augast now barely the last day of the month someone deposited large amounts of money into my account then boom bears takes my money mind you it’s not even the 25th. Clearly someone is monitoring my bank account this is a violation of my privacy. I should not receive money into my account because I owe bears ? This is nonsense
