Greenlight policy and old mutuals incapacity

Ive been trying to get to speak to someone regarding my greenlight policy but no one ever calls us back after leaving voicemail messages and asking for call backs online. I've tried to reach your contact centre so many times regarding my greenlight policy. No one ever contacts us if the policy doesn't get debited correctly they just ignore it and we trying to call everyday and due to short staffing we never get someone. I can't even pay for this policy online which is so fraustrating. During this trying time i think as a business old mutual needs to be more lenient with people around their processes its disgusting after so many years of loyalty we can't even speak to someone.
