Waiting for my ebucks reward

Hi, i have got a problem with fnb bank regarding the ebuck. In april 2015 i have opened a gold cheque account via phone. They called me and told me that if i deposit the money in to this account within 30 days atfer the account open i will get the a 5000 ebucks reward. I did deposit the within that period but i did not get that reward. I called the fnb sales team on the 15 july 2015 @ 15h45 and i spoke to Muzi Wanele 3071 and aggreed that i have supposed to get those reward and promise me that he is escalating the problem further i will be contacted within 48hrs but since then i have never been contacted up until now i m still waiting for an answer. They should retrieve the recording. I feel like i have been misled to attract me to open the account. This is a breach of contract
