Very disappointed in the service

I have had a policy with Absa Estate Provider Plan from 2019 which is 5 years and I'm a pensioner who never missed the policy payment however due to some financial problems it didn't go through in May and I received an SMS that it will be taken from the benefit then I called in June to make sure it will be debited the lady advised me it will go off on the normal debit date which it didnt go off and yesterday when i called in the guy told me because it didnt go in May that's why it didnt go and now is lapsed and i must pay 3 months worth of premiums for it to be reinstated i fell this is a rip of as a pensioner i was loyal and in all this time never missed a payment till i had some difficulties and wasnt even advised that this turned into a cash payment and not a debit .Absa please can you give me back the money that i have being paying for in the past 5 years you can take whatever service fees and mark the policy as paid, but i cannot let so many years of my money go into a loss cause your agent didnt explain to me to go pay cash. Please pay my hard sweating money back for your lack of communication .
