PAYMENT TO AN INCORRECT ACCOUNT NUMBER

On 15th April I paid my account with incorrect account number via electronic transfer ,I only notice that the transaction had an incorrect account number on before the 15th of May. I called Home choice and send and email with all the proof of payment. I again called them for a follow up the following week....that was actually 22 May until now no email reply or any call as they said someone will call. My account by now is over paid and I need my money back as we are affected by the pandemic but no one seem to care.
