False information

I am so disappointed, when applying for a home loan, I was told that upon its approval I need to open a bank account so that I can get R5000 worth eBucks. I went to the OR Tambo international airport branch to open an account and I even asked the person who was assisting me when are they going to load my eBuck, she said after my first instalment. I then also received an email from FNB Home Loan saying I won't get that anymore, they **** to me so that I can be their customer but failed to deliver on their side.
