Poor Customer Service

Resolve issues with better and positive attitudes. Karen one of the operators answered the phone rudely and didn't even resolve the issue we have. We have been waiting 4 years to get documentation from CNI and they simply don't comply. Karen kept on telling us she can't send the paperwork because she is busy but funny thing is, that paperwork is part of her daily job so I don't quite understand why we can't get the paperwork that we requested. She doesn't respond to emails and even after we made contact with her requesting the documentation signed because it was sent blank the first time, she refused and said we should stop calling her? So now I'm not sure how to get the provident fund papers.
