pathetic service and milking money out of us

I had 2 policies with Liberty Life and ended up cancelling one due to lack of service and their pathetic financial advisers.... all they care about is money. They just want to milk money out of us. They increased cover amount on incorrect policy which is still active with them. I sent a request on the 11th of July to reverse those changes but still not done. Every-time I contact their customer service I'm advise that there is an escalation for my query. Like for how does one has to wait to reverse changes that I did not request for on my done on my policy . Now I'm paying a higher premium for stupid changes done by the financial adviser Roche.
