Poor service

I opened an account with FNB and the cellphone number was incorrectly captured by their consultant as a result i lost R3000 because i could not get any sms update i logged the incident at Bennmore Gardens branch i was told the turn around time is 7 days no one called me i went to the branch again i was told to wait 3 more days i went back after 3 days i was told the incident is still in pipeline i dont even know what that is. Again no one called me today os the 19th of march i went back to the branch i was told the person dealing with my case is off and the other branch staff will not be able to assist with follow . So much for a big and so called "best bank" with such poor service.
