Worse service ever

I am still struggling with these people, they have put a default on my name after I have sent them proof of payment that they said I missed but payment went off as per the debit order that was scheduled, bank statement proofs it. So now I've submitted everything to the lawyers who are handling it and doing my follow-ups yet they haven't given any response. NEVER EVER WILL I BUY ANYTHING FROM HOME/FONE CHOICE AGAIN. *****S
