Shocking service - contact centre

Shocking service! Phoned in for assistance with something simple. Needed my daily limit increase changed, but there is an error on the FNB online banking system which enabled me to do the change, therefore I called the contact centre. Been holding on for about 10 minutes and the call was cut off. Called again, held for another 10 minutes, just to talk to somebody on a really bad connected line, we could not hear each other talking and the line was cut again. Mike Kiley, ***
