No Credit after a month - poor service

I logged a credit card dispute on 10 April ref ***. It is 19 May and has not been resolved. I had feedback from Fikile Tshabalala on 7 May this will be credited. Speaking to an agent on 14 May they promised 48H. Now I still have to struggle with the FNB secure chat to get this resolved. Seems like FNB has become comfortable with this type of service delivery
