NO SERVICE OR BAD SERVICE- CAN NOT SOLVE QUERIES OR HELP BUT SEND INVOICES TO PAY

This company takes your money - up your contract without your consent! DONT Help! HAVE NO CLIENT SERVICE! MAKES PROMISES TO SOLVE YOUR QUERIES AND THEY DONT! CANCELL YOUR LINE AND THEN STILL SEND INVOICES BUT HAVE ALREADY CUT YOUR LINE!FOR MORE THAN A MONTH WITHOUT INTERNET! I had to pay for a service that I did not received! I requested a refund now I am getting invoicing with double the amount I have agreed on! the contract was month to month and Broadband cancelled it in April already AFTER A FIGHT DUE TO NO INTERNET SERVICE AND THEM NOT HELPING OR SORTING OUT THE ISSUE. I have asked several times when it is going to end but they did not want to answer I paid for internet in April and there was NOT one day that i had internet connection. I Queried and have sent them Pictures almost every day, I was promised they will send someone to test the router that was faulty from the start and they never sent someone. I had to keep calling and they will promise they will call back in 5 minutes - they dont! Even after all my calls emails, whatsapps and pictures they still did not help me. My line is cut and now They keep on sendintg me invoices to pay! AFTER THEY KNOW THEY CANCELLED THE LINE IN APRIL. THEY KNOW I DID NOT HAVE INTERNET FOR APRIL. THEY KNOW THERE WAS A DAILY ISSUE! I HAVE SENT THEM ALL THE PROOF! Every time I call they would have another promise!!! FOR WHAT DO I GET INVOICES? FOR WHAT MUST I PAY? I HAD TO BUY DATA BECAUSE MY INTERNET WAS NOT WORKING - THEY GOT THEIR MONEY BUT DID NOT HELP AT ALL. HOW CAN THEY SEND INVOICES IF THEY CANCELLED THE LINE IN APRIL??? AND THEY KNOW I HAD NO INTERNET SERVICE!
