Annoyed

In all honesty, i have been with FNB for 3 months and have problems. It annoys me that i switched everything to this bank. I should have stuck it out with the other one. Firstly it was an issue getting my card, i waited 3 weeks and after getting pushed from pillar to post, i eventually said i will collect it myself from the bank, which i was charged an extra R100 for... I didnt complain as i was just grateful that i finally had my card. Then they offered me the overdraft facility and i app**** for it thinking it may come in handy at some point in the future. I went into the bank again on the 28 November, gave all my information to the assistant and was told that it would be active at my next salary payment....It was not. I even received a message via my app that the funds would be linked to my account...Nothing. then the 20th December i receive an email asking me for payslips.... As it was Christmas holidays, i was not able to do this and sent them a mail back saying my employer was out of the country and i would only be able to provide them with said payslips in the new year. New year started and we had a family crises and now i really need the overdraft... I went into the bank, with all 3 payslips, was helped by a lovely young lady, after speaking to a million people prior on the phone. she forwarded all relevant information through to the department and then i was sent on my way. It has been 3 days now... When i was offered the overdraft, i was told that i was approved and that it would be instant. i have friends who app**** for an overdraft, quadruple my amount and it was linked to their account in minutes. I would not have app**** for this again had it not been an emergency but my father passed away and now I need to assist my mother. I really thought i could count on the bank that everyone raved about. What do i do now?
