DOUBLE BILLED,NO REFUND TO DATE

I have a horrible experience with Edgars Brooklyn as i was double billed on the 30th/Nov/2020 while paying for my and mother's account,i was billed R700 extra and was told by the cashier and her manager that the debit payment will be reversed into my account within 24 hours but i haven't received anything to date.I have written 3 e-mails already to RCS and another Edgars e-mail address having attached my bank statement as requested by the store manager to these e-mail addresses was given with no help to date.As a front line health care worker during this COVID-19 pandemic i don't have the time to also add account worries whilst i have been paying my account and my 02 siblings account accounts for over 6 years.I wrote my last e-mail indicating that i will not be paying any Edgars account in my home as i've been doing for the past years as they are currently unemployed UNTIL i get my R700 into my bank account.I will also not account for any interest which will have accumulated during this period.
