Bad service from My Service Suite

I am beyone frustrated with the service I've been receiving from the 'Secure Chat' option on FNB. I don't know if the consultants require more training, or whether the system is just not working. On 7 October I app**** for a credit card limit increase to which R220,000 was approved. I then realises the next day that this was not actioned. I messaged the service suit and was told there is no application and that I would need to redo it, which I did on 8 October. I then received a message stating that the application is subject to a debicheck approval. Today is 10 October and I have not yet received the debicheck for approval. I need someone that has the knowledge and expertise, to please assist me asap.
