Prescribed debt

I keep getting calls for an absa bank account from about 10 years ago, which I closed when I was retrenched. I am now getting calls, about 10 years later to say I.owe money on this account. Not only was this account closed but any debt that has acrrued on this account (due to the account bot having been closed by absa and thus not being my fault in the first place) this debt would have prescribed ages ago anyway. Kindly close the account and stop pestering me, for something that isnt my fault or problem. Thank you
