Harassment

I cancelled my Cell C account 3 months before my contract ended in 2018 since then Shapiro shaik defries contacts me yearly monthly sometimes daily for apparent fees that was never paid. On 19 May 2022 I was emailed where Shapiro tells me that this account was settled. But still they harrass me for money that I do not owe. But wait theres more everytime that they phone or email they bill me.
