Threaten to cut service almost every month

Every month I pay my account. I loaded the EFT payment with a payment confirmation to be send to [Email Removed] My reference used, is my account number as requested.<br> This month they again wanted to cancel my service as they did not receive proof of payment. I thought that companies at least do a reconciliation from their bank statements before they reproach clients that comply with their payment terms. This month they stated that if they do not receive proof of payment they will move my account to Telkom. What more can I do?????? <br> I am not in the office 24/7 and connot jump whenever they can apparently not find my payment on the bank statement.<br> My accounts also vary in amounts even though I signed up for a combo. No credit on my account processed or even an apology.
