TalkTalk Chief Executive Dido Harding still remains confident of a turnaround, despite seeing broadband subscriber numbers fall again.
The broadband provider shed another 43,000 customers during the final three months of 2011, leaving the firm with a total of 4,079,000 subscribers.
This came after the same number of customers chose to switch broadband provider between July and September 2011.
But Ms Harding said changes undertaken by TalkTalk in recent months should lead to an improvement in performance during this year.
"We have continued to improve our customers' experience with further falls in customer service call volumes and an increase in the rate of online self-service," she added.
"As a result, churn has stabilised and we remain confident of a return to positive total net additions in the first half of 2012."
Ms Harding said TalkTalk's operational achievements and strong financial performance offer confidence for the coming year.
"We look ahead to delivering an exciting strategic agenda through 2012, including the launch of our TV proposition," she added.
