Disgusting service

Im trying to get a fibre line installed at my house, But Vumatel says I already have fibre. I DO NOT HAVE FIBRE AND IT HAS NEVER BEEN INSTALLED. They have admitted to making a mistake on their side but they cannot fix it!!!!! Absolutely shocking service from Vumatel. Wirulink is great and they are trying to sort the issue out, But Vumatel just dont care.
