Quick to answer when it's sales, not so much when it's cancellations.

I have sent exactly 30 email. yes THIRTY. Since 27.05. and i'll keep sending til this is resolved. im not paying another cent. I've requested settlement of contract amount, received, made payment, sent PoP. and now received another bill, due in few days time. I will return the debit order. No one responds to my mails, except a lady I dealt with when i was taking out the contract, but she's in sales, not cancellations. Obviously sales will respond. I want this resolved. WHY DOES NO ONE RESPOND. What the AF?!! Oh wait, i do get a response, automated that states i'll be contacted in 24-48 hours, and some that say 5 business days. All BS
