Worst service ever.

Their service is really terrible . I have been paying premiums for almost 5 years, all of a sudden they stopped deducting from my bank account. When I phoned I was told that banking details were changed and therefore the policy has lapsed. I communicated with a lady by the name of Nomathemba Mncwango, she asked me to send my bank statements of which I did. When I send her follow up messages she just ignore them.
