FNB e-Bucks

I have been reporting my e_Bucks that are not been updated to the rewards that need to be forwarded to my account. After numerous emails and reporting it to FNB I still have not relieved my updated rewards nor do FNB interested to back date my rewards that need to be paid to me after I have forwarded to FNB my bank statements from January 2022 to date. Currently FNB indicate a payment made by me to an non-Engen service provider that FNB cannot give me the date of entry. This is totally unacceptably and show the unprofessional service from FNB.
