Empty promises and bad service

Ive app**** for a loan online the 14th of december no reply I went in to the bank at woodlands on 23 december where a consultant phoned the loan department and said she is still busy with it and will phone me in 30 minutes it is the 24th december today still no respond. Ive checked my credit status that is good and cant see any problem why I cant get a loan or get a response. A other company offerd me a bigger loan that I app**** for at fnb but the intrest are more and I see it better to apply at the bank that I bank with. But if this is the way Fnb is treating me then I will rather move to a other bank
