Pathetic service & support

For the last month and a bit, I get pathetic service from this ISP. Anytime from 1pm onwards, speeds on a 10mb line go down to 0.6mb until 11pm. I have submitted multiple tickets and keep getting the excuses. I get ping spikes up to 3000ms in a discord locally hosted server. That latest bull, was they sent a technician on a call out and he said it was a tree branch in the way, said tree has now been removed, what he failed to mention was he also changed the AP I was connected to as he had to authorise the MAC on the tower, which is something that only happens when you change AP. So from Tuesday 16 Feb 2021 to around 18:00 Saturday 20 Feb 2021 all was well. Then they "upgraded" their tower and the exact same damn problem has come back again. I submit yet another ticket on this matter, some "genius" then switches my connection off to test it, reconnects me and tells me everything is fine, which it ****** well isn't!!! But wait, there's more!!! not only did the problem not get resolved, but the OPEN NAT that I did have turned back to a STRICT NAT status, so somehow, he managed to stuff up the firewall rules put in place months before. This is a service I have to pay R1299pm for? Not to mention the R350 callout fee they are now rushing me with on top. AND THE PROBLEM IS STILL NOT RESOLVED! Support tickets get no response whatsoever and I am not the only person experiencing these issues either.

And the best part is, they try give a generic response to the issues when they do respond, and I'm in the IT field , so don't try pull one over on me like you have been these past months.

Honestly, with the way you treat customers and conduct yourselves from a support perspective, I don't actually expect to even get a response from Herotel Breedenet Wireless on this matter, that is how little faith I have in you.
