Glade sending us **** proof of payment

Good day,

There was a competition running in December for glade, terms and conditions says we will get our prize in March even now there’s nothing in our bank , on Wednesday the 17th, glade sent us a **** proof of account claiming that they paid us on the 13th of July 2024 even today there is no money deposited into my account. I tried calling my bank asking if there is money deposited into my account and they said no. Please assist on this matter
