Billing query

Yoh, Telkom call centre agents and team that i have spoken to are so useless.

I have been calling Telkom to query an obligation amount charged on my statement for device i'd lost. for the past 3 months l had been told that i i'm paying the obligations fee for the last month, to my surprise when i receive my September Usage it still shows that i will be paying the obligation fee on the 1st of October. Two months ago i spoke to team leader named Eunice Mchunu, she advised that if i still the obligation fee August statement i shout directly email her of which i did, however she did not respond to this day. Can someone look into this for me ASAP.
