Woolworths Loftus has the most pathetic service

on the 8th of October 2022 i went to woolworths loftus to pay my account,however a week later i received a call from woolworths financial services telling me that i have not paid my account which came as a surprise to me because i was certain that i paid,I Went back to the the very same store to find out what went wrong the manager confirmed that the payment does not reflect on their system,He requested that i must bring proof of payment of which i managed to provide as well as my bank statement,The manager and the assistant manager promised to resolve the matter however up until this day i never received any communication from the store manager. I recently called the store and i was told that the head office can not locate my payment even though i have provided them with proof of payment and bank statement.
