FNB , how can we stress u ?

I kept on receiving messages from my phone that my bond is in arrears , tried finding info from FNB so that I can pay the amount in arrears as it is messing my credit profile , firstly there is no phone nr for the H/L department on the net ,I was asked to fill in my info and someone will contact me in less than 48 hrs , even today nothing. So really FNB should change their slogan to how can we stress u. Poor service from such a big bank.
