Mute the call before complaining about customers

<p>I was extremely disappointed by a recent interaction with RMB Private Bank. In trying to resolve an issue, I called the call centre a number of times. On my final call I heard Cameron make disparaging remarks about me to his colleague. Cameron - If you are going to be rude about customers, at least have the decency to mute the phone first. I resolved the issue by using my Nedbank card instead #RMBservicefail</p>
