Difficulty to get my, monthly annuity from Old Mutual, whilst overseas

I am a pensioner currently based in my home country, receiving treatment for cancer. I have an old Mutual Max income where I receive monthly payments on an investment I have with them. Currently I no longer have an active South African ABSA bank account, is currently closed and no longer in use. I asked Old Mutual to put my funds into my wife's South African bank account or deposit it into my Canadian bank account. Old Mutual said they cannot pay my income for life bonus into a third party's account, that of my wife, and they cannot deposit my money into the Canadian account, and they will send my money to the very same bank account that is closed. I tried to create another bank account, but banks need a SA phone number which I do not have. I am frustrated as I cannot receive my funds, If Old mutual cannot pay my income through my wife's account, can I cash in my funds or transfer into my Canadian account where I have another annuity, Calling Old Mutual customer care is a daunting task, you can't get hold of the agents, when you eventually do, the calls get cut. I need help getting my monthly income.
