AVOID - Overcharged and poor service. Early this year broadband was becoming more unreliable and eventually in March an engineer was sent who supposedly fixed the problem at the exchange. Our service continued to be unreliable but the next bill we received was double the usual fixed amount. The extra charges were related to calls but we had long disconnected our phone so were just paying a standard charge for broadband. Obviously the engineer had mixed up connections and that's why our broadband was still terrible but now we had calls added to our bill. Talktalk refused to believe us but would not provide details of the telephone numbers we were supposed to have called. After numerous conversations with customer service they eventually agreed to refund and said we wouldn't be charged again as we had decided to move suppliers as our contract had ended. However I noticed on my account that they intended to take a higher amount for the next month so I had to cancel the direct debit. For the last 11 days of our contract before disconnection the broadband wasn't working at all and they say I am not due any compensation. Still waiting as well for money overcharged in March. Will be making a complaint.
