Poor handling of overdue account

I recently missed a payment on my TGF account to the value of R46 due to circumstances where I was unable to make the payment on time. I was disappointed with the aggressive manner in which TGF payments department managed the situation. I acknowledge my error and accept responsibility for not honoring the payment on time but as I have been a loyal TGF customer for almost 2 decades, I have a purchase limit of R5000 on my account ( which I would never have if I was a poor customer I would think) and have always honored my payments diligently, I would have expected a bit more understanding and patience exercised given that over due amount was a miniscule R46 and was handed over and accumulated interest, yes I understand this is the process but surely some leeway should be allowed to customers who owe a minimal amount in comparison to customers who owe thousands and have been blacklisted with their accounts being handed over to collection agents, it seems like if TGF was in charge of our justice system then a shop lifter will be subjected to the same punishment as a serial killer, if I had to use an analogy to put context to my complaint. I am really disappointed and once I have paid up the account I will be seriously considering closing out the account and not supporting TGF stores in any way whatsoever. It is sad when loyal customers are treated like ********s these days.
