First time ever ,my debit order for telkom failed, the amount was R139

First time ever ,my debit order for telkom failed, the amount was R139. I only discovered this issue when I started getting messages from debt collecting company. I called telkom to resolve issue, followed prompts. Only to hear. FAIL, Instore manager could not assist, I went online, paid a double ammount of R343.76 directly into their Centurion account , no one can trace where this money went, I have emailed, the details, promises of getting back within five working days.. I am still waiting. Telkom then proceeded to deduct R518.19 and R172.73, getting hold of a live person to assist is a nightmare, so from owing them R173..I accept the 200 rand penalty, however. I paid on time and in advance..my financial loss, is still unresolved, to date. I only have a case number, no call from telkom, the credit card company guy asked me not to complain, keeping in mind my track record in paying only took one oversight ever, hope this assists others in knowing how telkom operates
