WHAT THE HELL VOX AND OTHER PROVIDERS ????!!!!!!!!

I have been doing IT for over 2 decades. In my time i knew Webafrica was great for a good period of time. have become **** so i went to rsaweb rated as #1 in SA. Had so much **** that even though i dont use them im going to report them now to thencc. I moved to vox who came in the game not long after webafrica and internetsolutions who were actually the best ISP in SA and vox has slowly become one of the top and i helped many of my customers with vox and vox was great but too pricey but now i can afford vox and decided to go to vox and its been pretty good except for my international bandwidth being half the speed it should be causing problems for me and i complained about it for quite a while and i was told it was checked but it wasnt. My router started giving trouble so vox was here on monday to swap it but walked into my house with a mesh system asking me where do i have trouble with wifi so their tech didnt even know she was doing the wrong job. She went back to her vehicle and got a router and configured it. I did speed tests and it was all the same, but the rebooting everyday was solved so there was a issue with the router but it wasnt what was affecting speeds. I complained on monday and sent screen shots. I sent emails asking them to change the ip address of my router and setting a dhcp pool and a reserved ip address for my pc and gave details.. I asked them to sort the ports on my router so i can get into my dvr system from outside the network and on the network because its on the wrong ip address pool .. i asked them to enable the ddns. Nothing has been done.. in 4 days nothing has been done. absolutely nothing.. and no one has rep**** to my emails. no one has called me.. no one has fixed anything.. but i get the read reports saying my emails were read.. WHAT THE **** IS GOING ON WITH PROVIDERS IN SOUTH AFRICA DOES NO ONE GIVE A **** ANYMORE ABOUT THEIR CUSTOMERS THIS GOES TO ALL ISPS.. *** ANSWER ME AND WHY IS NO ONE DOING ANYTHING ABOUT IT> ICASA WONT EVEN HELP ME INVESTIGATE RSAWEBS UNGODLY PRACTICES AND ITS ALL ****ING BULL**** I CANT TAKE IT ANYMORE> IS THERE ANY GOOG ISP THAT LOOKS AFTER THIER CUSTOMERS? DO ISPS NOT CARE IF THEY LOOSE CUSTOMERS >> SOMEONE PLEASE ANSWER ME FOR THE LOVE OF GOD WHY ISNT ANYONE DOING ANYTHING IS OUR NATION SO ****ING LAZY ??????
