Bad service

Discovery Life is unable to update premium of my policy. The fact that I was send consent and confirmation form to sign a week ago and my query is still not being resolved. Instant I keep on calling from one consultant to another telling me that the query is with the underwriter's of which their turn around time to complete the process has past. And On top of that they send the same form to sign AGAIN, why must I do that? BAD SERVICE with no answers.
