MTN - Confused Space Travellers

On 21 May, we got a call from MTN employee, Ntsudzuluseni Mutheiwane, who said that my husband P Alting needs to pay by debit order on 01 June. We advised him that we asked the debit order to be cancelled and would be paying cash, as there won't be funds available on 1 June. 2 SMS's from MTN were received confirming that we are now on Cash Basis. I received an email from Ntsudzuluseni asking for copy of sms. This was sent to him same day, 21 May 2020. On 29 May, he sends an email saying to ignore sms, account is still under debit order. I advised him no funds will be in account. Debit order for R131 was returned and a further R145 bank fee was charged by Nedbank for this return of debit order. MTN must consider their account paid as we specifically told them that no funds would be available. We can not afford to pay MTN as well as Nedbank. So MTN, please sue us! You are an *********** bunch who wants your pound of flesh, even during lockdown! Disgusting and needless to say we won't be renewing a contract with you.
