ABSOLUTELY ZERO CUSTOMER SERVICE!

I have been a customer for over 2 years, and have continuously had issues with my fixed LTE speed. I work remotely, and need reliable internet. In April 2024, my speed dropped to 1Mbps, and it was affecting my work. I requested they cancel my service. They came back to me and eventually resolved the issue, so I advised in writing that I was happy to continue with them. Then 1 June 2024, my internet is disconnected. I Whatsapp, email and try phone. I get a reply to my email, from Zelda, saying I don't have an account with them. I immediately reply advising that I had requested the cancellation request be cancelled and that I need my service back up and running ASAP. As of the 2nd of June I have yet to receive a reply to that email, my WhatsApp messages OR the message I left on their phone line. This is the worst customer service, in fact, it's NO CUSTOMER SERVICE - bad customer service would at least mean you get some form of help, even if it was poor. I have also requested a cancellation of the cancellation via the website, hoping that would speed things up, but they have no support on weekends it would seem.
