Poor Service and no feedback from African Bank

My numbers are and has always been *** & *** My Work Number has been and is *** since 17 January 2011. My e-mail addresses has been and is bertus@mccoysglass .co.za and ***. I missed 1 call because I was busy on another line and called back immediately only to be blocked (prevented me from talking to the investigator) by the person that answered the call. I have also send 3 e-mails where African bank acknowledge receipt and undertook to forward my mails to the right department and person with no response. When I phone I spend anything from 10 to 30 minutes on my cell phone to be able to respond to SMSs that the bank send with feedback. I do not have other missed calls from the bank, no e-mails and they never contacted me on my landline at work.
Make one wonder how desperate they are to render good service and retain happy customers.

Just phoned African Bank again spoken to Mpho same result she will send an email to forensics to contact me (spend another 15 minutes plus on my cell @ a cost of ± R 40.00 to get nowhere).
Believe the person working my case is Jabulani. My question is do African Bank treat al their customers like this or am I the only one and for what reason.
