Extremely pathetic service-FURIOUS!

I had been trying to use my Nedbank account and it kept declining. I had somebody try and deposit money onto my account 3 times and it rejected. i had called the call center-call ***. The lady advised me that my account was blocked- how can my account be blocked and you not notify me? , the agent that took my call put me on MUTE for long periods and then once i asked to speak to a manager she put me on hold for 15 minutes before dropping my call! this is absolutely ridiculous. My account was previously frozen and the call center was able to assist me(Please note that this was in July 2014 with ref number ***6) i had to call your call center after having the call dropped by the previous agent and spoke to Bridgette who transferred me to a manager named Lindi(ref ***1). she promised me a call back as she was to investigate my query. she did not call be back as promised. Another manager named Prisilla called me and she advised me that the previous manager **** to me. How can your managers be on different pages and not have the same understanding of your systems. i eventually went into the branch as i was told to by your call centre.My account is still BLOCKED
