Hollard Life is at fault here

My experience with Hollard is terrible !! A Funeral Policy that started in 2003 and all off a sudden I receive an sms 01/04/2023 stating that the policy has been stopped due to 2 payments not received. I've called them more than once and send countless emails with no responce. I send them proof of payments and they told me it was not allocated but no futher response from them. I also told them I can't make further payments unless their problem isn't sorted out and that was already just more than 2 months ago ! My last email I send was telling them that my next step wiil be Hellopeter that does not even seem to bother them !
