Unfair cancellation of policy

I would like to express my great dissapontment with Metropolitan life. I have never heard of such bad customer care and service, ever? I took over my mother's policy due to the fact that my sister has passed on. Even though I was not finnancially ready for this I felt I had no choice but to continue with the payment of the premiums. I have been peying the premiums ever since. To my surprise when I called in at the Call center to find out on how do I get a copy of the original contract of the policy, I was told that the Policy was cancelled.I expalined my story to the call center agent and was told to pay 2 premiums and send my banking details so that I dont pay by EFT anymore and the policy would be re-instated. I payed double the premium and sent through all the relevant documents. To my astonishment I have just recieved an incomplete SMS notifying me that the pilicy is cancelled and will not be re-instated. I do not get feedback by email anymore from them now ?Why would they ask me to pay double the premium and send my bank details to them so that they can debit my bank account in future yet not re-instate the policy. I find this to be very unfair as the policy has been active since 2010. 7 years later they choose to cancell it without any correspondence? This is the first time i recieve an sms from Metropolital, now only... to inform me about their failure to re-instate. I would like them to re-instate the policy with immediate effect. I feel there is no justice being served to me. There is a lot of money that has been paid for this policy I cannot afford to have it cancelled.
