Discovery bank staff *********** and negligent

To whom it may concern. I would like to lodge a complaint about Discovery staff who are either negligent or **** to me when i requested a debit order date change as per “CASE #[***] - Change in Payment Date” I requested that my credit card payment change be changed as to be in sync with my salary date. I could not update it myself because the email address to which Discovery sent OTP is no longer active as i left the employed 8 years ago. Discovery could not delink this email address from my profile. My new debit order date must be the 7th of each month. I received an email from Caitlin only on the last week of September confirming the new debit order date. Today 5 October 2020, i receiving messages informing me that i failed to make payments on my account and therefore the account will be locked and attract penalties. Your failure to make this change is adversely affecting my credit profile. 1) I therefor request Discovery to kindly revoke all the penalties charged on this account due to the staff negligence. 2) I also request discovery to confirm with proof that my debit order date has been updated. 3) I also request that my old employer email address (s***@no***.com) linked to the life cover taken around 2*** be deleted from my account as it it preventing me from making crucial updates or access to my profile.I hope all is in order.
