Bad customer service

I have been calling them to report my fiber wire which got cut since from the 11th of February 2021 to date nothing has been done. I get told my case is still opened and was assigned to a Sinalo or Sinazo wha has done nothing. I have spent a lot to airtime calling them and they couldn't be bothered. Have been put on hold for over 30mins waiting to speak to a "manager"
