Failure by old mutual to update details on funeral policy that they covered incorrectly.

I opened a funeral policy in February this year to cover my partner. Months later i discovered the name and surname was incorrect on the policy. I reported it to Old Mutual and sent them all the necessary documentation. I am still receiving emails regarding this policy that my partner details have not been updated. So im basically paying a policy covering someone that i have not requested be recovered and old mutual keeps requesting documents from me that I have sent to them months ago. I wish to cancel this policy and be refunded for the 10 months that I have paid because I am paying for someone that i do not know. After sending them the correct details twice.
