STILL waiting for assistance regarding my last complaint

FNB, I am STILL waiting for assistance regarding my last complaint: ***

I received two phone calls from you guys by way of resolution, however they happened while I was on work calls with clients (so I obviously could not answer). No calls came again thereafter but a voicemail was left for me to call the client resolution centre ***). I have done so numerous times and guess what - I am again each time placed on hold for ages. When given the option to leave a message, I am told by the automated voice that the mailbox is full! (Nice to know you guys attend to your complaints so regularly. Unless, of course, the mail box is full just from today. Very possible.)

I would like a call back on my cell TODAY please. And if there is no answer, please don't give up so easily - I use my cell for work calls periodically throughout the day (8-5pm). If you can't reach me once or twice, it's very likely you will the third time.
