Sim Card Blocked resulting to loosing my policy

My name is Phumelele Mdakane my ID *** , my number *** My sim card was blocked during 2020 lockdown period i contacted Jabulane Mall and they ask me the five number i have called of which i do explained no one can i called since i lost my hearing 2007. is where i lost my number that affected the policy with hollard where they indicated they send messages to the number. My husband try to contact Vodacom of which was unlucky as well due to the fact of the five contact number used before the Sim Card blocked. I will be happy to get the matter resolved since it affected me a lot. Pep policy i have wo policy one is not active but both I'm paying them on the same day but , problem begin during the lockdown where they was a lot of challenges and premuim also increased but continue to pay . In the first instead there was no paper when joining the policy at pep store . Thank you in advance for helping
