Since July 2015, still waiting for someone to call

My son turned 21 in June 2015, so I called to inform Old Mutual to inform them as one would think they have this on record and would alert the client. But instead I called as it is a concern that he would have no cover should anything happen to him. After updating records etc. it was accepted that he'll be on his own policy but still be paid by me. 1st debit order did not go through for whatever reason, I called and they submitted again. Then the debit order suddenly went of on the 25th of the month which can end up being returned due to insufficient funds, fortunately it went through. This does not suit me so I called in August and now in September 2015 to sort this out. The Call Centre Agent spent time with me to take all details etc. and told me someone in the relevant department will call me back. Wasting my time to explain all of this and no one called back. And also no revised policy schedules received etc.. Has Old Mutual grown to Big or is this just a matter of No Interest ?
