They are a *****

I ordered a fibre to be installed in april 2022, which i was told someone will call me to set a date to come install in few days i waited with no call from anyone but to my surprise they delivered a router so i was happy thinking its gonna happen, nothing happened after more weeks of waiting i called to cancel as i was working from home and needed the connection badly. After moths of them not saying anything or calling or emailing i get an sms end of august to say my account is in earears, but what account so i call them they say i owe 900 for a router that was delivered in april and will get an email with details but guess what no email. To my surprise on the 2nd sept they deducted 1797 how did it now change fro 900 to almoust double in couple of hours... And i still have the stupid router untouched by the way, the person i was even talking to was really horrible over the phone even when i told them i didn't receive an email with details you guys are a *****.
