Worse customer service and lack of comminication

I have been calling Old mutual customer care for more than 5 times and I cant get through to no one it keep on saying repeat one thing over and over again. Then i emailed GS Enquiries asking one the consultant to contact me and no one has called me. I have new banking details of I need to inform them with before the debit order date but no one is calling me back. I'm worried about my policy.
