FNB false promises

FNB fooled me with the following: Why not open an FNB Gold Cheque Account TODAY for R109 p/m & Get rewarded with R1000 by FNB. Reply YES = Call / Stop = Opt Out. Free SMS applies. Ts&Cs apply. The FNB consultant phoned me and said that the first R500 would reflect once I download the FNB app on my phone and the remaining R500 when a deposit of R5500 or more gets deposited into my account. I've met al the criteria and nothing happened. Why reel in new customers and not keep to your promise? I've been banking with Absa fot mor than 9 years now.. I regret moving
