Horrible Service. Life Cover Cancelation

This is the 2nd month where I am still waiting for someone to contact me. I have just been informed via your Facebook chat that my life cover was cancelled in December 2019, yet in January 2020 I called to make amendments to my policy and was sent a letter of confirmation that changes were done and January and February I was debited, in March I was not debited and I assumed there would be a double debit in April, again in April there was no debit order thus I made a EFT payment whilst I was waiting for someone to contact me as I had requested a call back but I never received it . I will require a refund of all monies paid out since my cover was cancelled without my knowledge and yet I continued paying. Please assist in this matter urgently.
