Dispute over call out fee

I would like to dispute an amount of R 266.85 on our January account - this was for a call out fee. I reported our line in January because it was extremely noisy and most times we could even hear the person at the other end of the line. From many past experiences, I know that we have to report the line as soon as possible because with Telkom it can take months to fix the problem, and there is thus no time to wait around to see if the problem will fix itself (because that is how you make it seem). Somehow, when the technician arrived, the line was working and now Telkom has charged us for this.

I do not agree that we are liable for this expense as I am 100% sure that it was a line problem (that was somehow magically fixed) and not an instrument problem. We bought a brand new telephone instrument by the end of 2017 after too many fights with Telkom over our ADSL line, and I am thus sure that the instrument is working fine, it was even tested numerous time late in 2017 by Telkom technicians. We even tested the line with a different instrument and found the same noise issue and this makes me even more certain that the instrument was not the problem. I have the feeling that someone fixed the problem behind the scenes before the technician could get to us, and that made it seem like there was no problem. It happened in the past that a Telkom technician told us that someone before him messed with our line's cables at the pole.

We have paid our account for January, excluding the call out fee, and would like you to credit that call out fee amount on our account. If the technician came to my house, tested the line and found nothing wrong, then tested the instrument and found it faulty, we would have paid that amount, but this was not the case. Our line was faulty before the technician got here and then it was magically working when he arrived.

We canceled that ADSL line because we could not stand dealing with Telkom anymore, and if things like this incorrect call out fee keep adding to our account, our landline will follow suit.

The contact details attached to this complaint is my father's as the account is in his name.
