Appalling service

It all started 3 weeks ago when i app**** for a credit card. I approved all the quotations and agreements and pity I have not yet received any confirmation via email and on the app is showing I have verified Debi Mandate, ) . After touching finishing I asked the Aspire Suite customer services to query the R1500 Superbalist voucher I was promised to get after a year till to day I have not heard anything, i tried phoning fnb's land lines, which is the most useless under the sun as no one knows what they are doing and keeps transferring you from department to department. I went to fnb Century City, Salt River and Mitchell's Plain they tell me to contact a number they gave me and that yielded no good. After phoning the numbers I was given i was transferred about 17 times between agents/departments/fnb new credit applications/existing customer applications/ credit card fulfillment and whatsoever and no one still up to today can tell me anything as i personally feel that employees at fnb is untrained and do not know what they are doing except to sell something and forget about the rest. I'm really frustrated at this moment as i don't know what to do as nobody at fnb can advise me anything. I've asked them to transfer me to customer service centers, and the lines drop. I've spent more that R200 on airtime trying to resolve the sh*t with my credit card account. If you requested multiple calls from customer service / managers to phone me regarding my service i'm receiving, and nothing absolutely nada is being dealt with regarding my issues i'm having. Their secure chat is just as useless as phoning them. Waiting for a response is like waiting for a million rand to fall from the sky. I have had it with you guys I want to leave this BANK ITS USELESS.
