Edgars terrible customer service - possible *****!

My Edgars account 'seems' to have some ********** activity on it or its just not being processed correctly. My purchase was returned to the tune of R2200 on 19/08 and instead of my balance reducing by that amount it went up by that amount. Following me picking this up (29/08) i've called Edgars credit department, i've emailed them, i've filled out website queries all as recommended by their online portal; all with a view of getting a transaction listing for a two week period. Nothing comes back until 03/09, a week later, when i get sent a statement that i could pull myself from the website for the beginning of August. I've been a customer of Edgars for about 17 years and the only time i have a query regarding possible ***** on my account they're unable/unwilling to help - i get the phone put down on me when i tried just now (04/09) to speak to their call centre again. I'm at the point of wanting to close my account due to this complete lack of customer service. I shouldn't even start mentioning how i was sent emails back with other customers' details on it - i can only imagine how my details would possibly be sent to other customers!!! I wonder if Edgars is aware of POPI!
