Extremely bad client service

I've tried to contact Nedbank MFC numerous times to finalize my shortfall claim. The claims agent has never contacted me since our last telephonic interaction where I was questioning the debit order that had went off. Every time I try to call for a follow up I never succeed in reaching the agent. The last time, even getting through to her line Manager Nokthula was also not successful. I've even went as far as emailing the complaints department, no response from them either.

I spoke to an agent last week who mentioned that I would be contacted before close of business that day, needless to say, that didn't happen.
