Despicable services from Herotel

I had continuous fibre down time for the past year using Herotel. I'd log a call or email reporting the problem and it would work once again. Sometimes in this month of June 2022 the line went dead for 3 days while i worked from home. I contacted the help line to perform a remote login to assist (using my own data, cell phone and laptop to which it failed. On the Saturday morning a technician came out (i was not informed prior to a callout) and again, my cell phone, data and laptop, was used to reactivate the line. No job card provided and no acknowledgement of a callout fee to be paid. I received a sms after the 15th June indicating the claim from Herotel of R749. When contacted, they exclaimed the charge was for a callout, again, no proof was supporting this. So it seems as if Herotel is not a Hero but a ***** with sticky hands as they can just debt your account for their faulty and failing network. And again last night, 23rd June there was downtime to which I didn't bother contacting them.
