Lies and dishonesty..poor service

On the 23rd September 2021 i paid my installment at beares lephalale branch, and on the 25th they debited the installment even though ive already paid, but i did not blame them for that..instead i went to the store on the 27th to inform them trying to get my 750 back, they asked for my documents i gave them straight away they said they could give me cash but unfortunately they dont have , of which i understood, we decided that the money be reversed through back to my account as i couldn't reverse it bcus its not reversable, fine the next day i did a follow-up they told me they have sent the docs to headoffice they will pay me back, on the 4th i called again the said they will ask people from headoffice but no straight answer but thy told me they normally pay 3 to 4 working days, its been past that, today i called headoffice and explained , the lady told me that she can see my problem on the system but im gonna have to wait another 3 to 4 workig days for a feedback, a whole lame feedback for my R750 thats not even theirs..im so ****ed beyond annoyed..i cant wait to pay the rest of the money and never buy at lewis or beares again
