Useless and unrealiable

Wish there was a -10 option. I have been trying since Sunday (07/06/2020) to report that my line is excessively slow. I am supposed to have a 20Mbps line, but it pings on THEIR test UNDER 10Mbps. When I sent the WhatsApp, I got told to test the line on a 5G Network, or plug the line into my Laptop... I have explained that I do not even know where to get a 5G Network and when I try to connect the laptop, I can't connect, as I don't have the passwords? I am NOT impressed with their lack of assistance OR lack of even trying to assist. We got sold out by Nepic, and have had endless problems in the complex since they took over. Their website listed e-mail comes back as an "unattended mailbox" and calling their landline is even less helpful. DO NOT EVER USE THEM. ASSOCIATED WITH MTN SHOULD ALREADY TELL YOU TO STAY CLEAR!!! I am also paying Nepic rates, but they advertise for cheaper with Supersonic. Been trying 3 months to sort the billing out.
