Regret switching

I am sick of FNB treating me like ****. Their communication is non-existent. I submit documents as requested by them, 3 days later I get a mail asking me to submit the same, damn documents again! What. The. HELL. I am honestly regretting switching to FNB from Standard Bank; Standard Bank, please forgive me! I didn't know it would be such a hassle with a bank that boasts that they're the best when in fact they're not. I have had to apply for my credit card literally 4 times, and every time it's a story as to why my application hasn't been processed (when I've been told 3 times that it's been approved). So while I'm here, waiting for my credit card to be delivered, the damn thing is not approved on FNB's side, with 76 different application numbers and stories/excuses. I'm sick of it and this bank already. Can the communication internally please be improved, as none of you know what the hell is going on. I have signed and sent back 2 application forms!! I REFUSE to go through this damn process again. I want my credit card delivered to me by Friday next week LATEST, otherwise escalation will be experienced by this idiotic bank! For flip sakes!!!
