Dispute not sorted out yet!

My mistake - I paid my account into another Telkom account - that I acknowledge. On the 8/9 I phoned Telkom and informed them of this - sent in proof of payment as requested, on the 13th I phoned back and was told that no pop received, and I must resend it - and a dispute must be lodged, which was done. On the 19th Sep, I phoned again, no pop on file and the dispute apparently was sent to the incorrect dept - it will be sorted out. I phoned again on the 26/09 - once again not sorted out - the person from last call sent it to the incorrect dept again. This is ridiculous - when can this be sorted out?????? I am going to be charged interest also, my account shows 2 months in arrears.
