Inability to resolve customer issues

I have had a life cover and funeral cover with old mutual for almost 4 years now and my payment have been on stop order, to my surprise I received a non payment notification on the 4th August 2020, I tried calling them on the provided contact numbers and emails I can't get through to them, financial advicer can't assist me but when I want to open a new policy they are very open to assisting, now my policy is about to lapse. I am canceling the policy with them!!!!
