Terrible service from FNB been calling and calling.

Good day I'm not happy with the service I'm getting from FNB I feel like I'm not being assisted correctly meanwhile I'm getting charged for something I don't want. I mistakenly clicked on the premier card upgrade and now on my app it's showing me the silver card and not my gold card I have called twice and been told the same thing that the request for downgrade has been sent through still nothing is happening this is an inconvenience and not acceptable and I will be closing my account and move on to another bank that will assist me immediately and not waste my time and airtime and won't recommend fnb to any other family members.
