Metropolitan did me dirty

I have a life policy insurance with your company. When I joined the policy, everything was well and good until the advisor tempered with my persal and increased my premium without my knowledge and concern. Then I logged a complain whereby I received a Refund claim form from your side and was advised to do an affidavit and send it through. I did all of that, mind you all of this was done in March, to this day nothing has been fruitful from your side. When I go to the branch (Winternest) to be precise, I get sent from pillar to post. 1st time I was there, It was in April, I spoke to the finance department consultant through the phone and she told me that the refund will be calculated and I'll be reimbursed after three weeks, still nothing. Went for the second time, in August/September the consultant told me to forward her an email and she'll Cc me whenever she gets a respond. To this day NOTHING AT ALL HAS BEEN DONE :(
