My policy should be resumed in the next coming 7 days

I would like to be assisted on this matter with Vodacom insurance. They sent me an email saying I have claimed that my phone got lost on the 26th April 2021 and it was still active/ in use with the number too until early May 2021 but to my surprise I have been using both the phone and number from the 21st December 2019 and never got lose nor claim to have lost the device. I emailed them back and they later sent a reply to say my policy has lapsed last year on the 7th January 2020 because they couldn’t get the first premium and that is a lie because that was not my first premium as I have started the policy in 2015 when I first had a contract phone with them. They have been debiting throughout all these years until this BS happens that I have no idea of.
