Non existent customer service to cancel a policy

I am very disapointed in Absa, have been banking with them for more than 20 years and never thought that the service to cancel a policy will be so non existent. Firstly been phoning to cancel my credit life policy and no calls gets answerd for more than 2 months, finally someone answerd after 38min of holding (previous calls just get dropped) Sent my signed letter to cancel my credit life policy along with my id and just dont get any feedback.
