Poor handling of Policy

Attempted to contact the company to update my policy however the line wasn't going through on various attempts.. I then kept on requesting them to call me back for weeks but no one contacted me. Reached out on email and still the response was very poor and needed me to follow-up with them asking for help for weeks. When emailed the requested document,the person in which I was liaising with still have not gotten back to me with the final ammended policy documents with the changes. Not sure on what to do next,please help
