FNB no service

I ve been trying for 3 days now to get a account confirmation letter on my credit card out of FNB as this service is not available online for credit cards. Every day I hold on for long or get cut off and have to phone again. I was given ref numbers but then the next day they cant pick up the ref number! REALLY FNB is this soooo difficult???? My personal banker is useless Ive been a private client for years. Where have your service gone???? I only need a letter!!!!!!!!
