Telkom not deducting manual account payments

Despite doing manual payments at PicknPay (Hazeldean or The Grove) every single month for my account ********** 08, my bill keeps on showing that I am in arrears. So that money is going somewhere but it is not going to Telkom. It appears that my internet has now been disconnected, possibly due to this 'overdue' account. I have supporting documentation for every month. Kindly resolve this ASAP. Or contact me.
