Bad service

I had 3 policies with Liberty but I canceled 1 policy long time ago. On the 23rd of Nov I received an sms about my refund that has been deposited to my bank account and I was not aware of that they did not communicated that with me. I went to the Branch and they told me that they were still deducting the premiums of that Policy that I canceled and it mounted to 7200 that was when they explained the process.The problem is that they deposited the money to my old account. They should have called and confirm my banking details before depositing the money. The account that they used I gave them 2/3 years ago they should have communicated with me. I called their head office they were shocked that this process wasn't communicated with me. They said I must write an email and I did that and no response. B. Xozwa ***
