Incorrect payment

My debit order did not go through last month so I paid them when I got paid on 28 May 2026. I got messages saying transactions had been declined this morning due to insufficient funds. I knew I had funds for what I wanted to pay. I then went into my account and saw that my money was taken off for my subscription. I got a message the other day saying it had not been paid. I phoned the office regarding my subscription and they said that the message had been sent in error. I now sit with a dilemma of not being able to pay for petrol and prepaid electricity among other things until I get paid.
