FNB poor customer service

I am extremely disappointed with the poor levels of service from FNB. I posted my experience last week on Facebook and Hellopeter and still no response from FNB. Is this how you value your clients? I had to book flights via ebucks travel and coud not secure the discount for my wife and kids even though I have FNBy accounts for my kids linked to my account and my wife is listed as a spouse on my FNB account. Added to the disappointment, I went into a FNB branch to confirm the criteria to benefit from the discount and was assured I meet the qualifying criteria. So let me be clear to anyone from FNB that may be interested in resolving this complaint. Kindly apply the discount to my flight bookings and refund my ebucks and cash shortfall i had to pay in due to incompetence from various staff at FNB. This is how you "can help me"!
