Edgars incompetency

I closed my Edgars account in May 2021 I did it instore at Lakeside Mall Benoni I paid the settlement amount...spoke to head office and was told that the account was closed I was a edgars club member and had a Hollard funeral policy as part of my benefits They failed to cancel the policy and keep on charging me for this They have now handed me over to a debtcollector after I have tried through many calls and emails to settle this matter ..Edgars have these on record I contacted Hollard and managed to cancel this policy yesterday What do I do??
