Home Loan Insurance - HOC

My bond was registered 30 April 2015 and I took Comprehensive Home Insurance from OOBA which was the cheaper option with same cover. The policy was forwarded to Standard Bank by both the Attorneys and OOBA and we also received proof of the submission. Yesterday morning we received an email from Standard Bank Insurance congratulating us in taking their insurance. I called the number provided and received confirmation that the OOBA policy is not in place. Apparently this is how Standard Bank roll in forcing clients to take their product. Please cancel Standard Bank insurance with immediate effect and place the OOBA policy on file. I do not want to have duplicate premiums at the end of the month.
