Telkom accounts no transparency

I am writing this review on behalf of my mother. My mother who is a 65 year old lady had her phone disconnected for the month of August the reason was that the amount of July was unpaid. This was found when a call was made to the telkom call center, it was said that a proof of payment for the month of July must be emailed to the accounts department and it will be resolved, then they rep**** to say a further R703.73 is outstanding and R729.71 current balance. But not mentioning which month is outstanding. My mum has proof of payment for every month why can't they be transparent and say send the proof of payment for the month of... So that we know which month is outstanding. My mum has been without a phone for this whole month and due to her being a risk during covid it is her only means of communication.
