Siphiwe Thedise NCR bad service

Good day. I have lodged a dispute to NCR regarding a Wesbank account, which states that i am 6 months in arrears,that information is incorrect. On the 26th of November 2024 i sent an email to complaints department regarding this matter. Siphowe Thedise is the one handling my matter. Every time i call the NCR, the switchboard always promises me that they are sending an email to Siphiwe Thedise and that he will get back to me by the end of business day.This has been going on for weeks. I want to complain about the poor customer service received or lack of from SIphiwe.
