Capitec - Defamation of character

Capitec blocked my account because according to them there was something wrong with my ID. To my knowledge this was based on a visual inspection on a copy of my ID.<br> <br> I went back to Home Affairs Heidelberg where I got the original ID and app**** for a replacement, on receipt I took it to Capitec Meyerton branch. To date my account is still blocked and Capitec keep on treating me like a *********. I don't understand why Capitec cannot confirm the validity of my ID with Home Affairs.<br> <br> Surely this amounts to defamation of character. Does anyone have experience with this? I would really appreciate some advice on how to take this further.<br> <br> Thank You.<br>
