Talk talk do nothing to resolve problems- they would rather stick more money on the account and hope you pay it. I cancelled and they had told me my payment was successful, I thought great I do not have to deal with them anymore. But apparently they had no record of me paying And had sent a 'final bill' even thought they told me I paid everything. I rang them up to resolve such a problem and they said they would try sorting it out- they did not. Instead after not ringing back they passed it onto someone else. It may be the cheapest but it's the worst in my opinion.
