Edgars doesn’t wanna close my account

Edgars doesn’t wanna close my account,on the 30th of October 2020 I visited Edgar’s cresta mall and I requested that I need to settle the amount and close the account,staff helped me to make a payment and called the call centre to help me close the account, I was given a phone to speak to the call centre agent and she promised me that the account will be closed and I I will receive an email,after three weeks I receive the statement from Edgar’s noting that I owe an amount of R55, I went back to the store and asked them to rectify that cause i didn’t know where the amount was coming from,they called the call centre again and I was told that the account won’t be closed until I pay that amount so I immediately paid that amount and I requested a paid up letter and I was not given one and I was told that they will respond with an email to confirm that the account is closed…unfortunately till today there’s nothing or some sort of communication from them…I was not taken seriously
