Heavily advertised TV deals attract 1,000 new customers a day.
Complaints about TalkTalk have almost halved in the past 12 months, the broadband provider has said.
The communications regulator Ofcom received 40% fewer complaints from TalkTalk customers in the six months to Sunday 30 September, 2012, compared with the same period in 2011.
In fact, complaints about TalkTalk - best known for its broadband, phone and TV bundles - have fallen by 66% from their peak as the firm continues to invest in improved customer service.
TalkTalk chief executive Dido Harding said the results were a "strong platform" from which to build towards future growth targets and further improvements.
"We've successfully launched our TV proposition and have installed 29,000 customers to date. Customer feedback has been positive and we are growing the base according to plan."
She added that the heavily advertised TalkTalk TV service, based on the non-subscription set-top box YouView, is currently gaining 1,000 new customers a day.
The provider's fibre optic broadband now has 22,000 users - approximately four times more than at the end of last year.
At the start of the year, TalkTalk was voted the company with Britain's "shoddiest customer service" in 2011 by Daily Mail readers, becoming the first company to 'win' the Money Mail's Wooden Spoon Award two years on the trot.
