Unprofessional client service

I've been a client of Doves funeral services for almost a year now, they decided to close their Moorreesburg branch which puts me and many other clients in a difficult position, firstly here is no representative for doves whom we can contact for assistance and secondly our payments, we don't know if they get our premiums at all, when I started my policy with Doves I was told by the office manager that I will receive a sms each time I make a payment. All went well until they closed the Moorreesburg office and said we could make payments at various service deleviry points. I paid my premium at ABSA as I am a client at ABSA too, I made the payment on 3 December 2019 and have not yet received an sms. Now should one of my family members who is on this policy pass away and I end up at Doves and they claim I have not paid and my policy has been suspended, since I don't have any proof of any kind that stated I made payments, who is going to carry that cost, this is poor service delivery on Doves side since I sent their head office an email and this office has not yet made any effort to mail me back,
