I've been with TalkTalk for about 10 years due to this feature. https://community.talktalk.co.uk/t5/Articles/Your-monthly-allowance/ta-p/2204660
It allows you to specify how much you wish to spend on calls (in my case) outside of any inclusive mins in your call packages. Once exceeded, TalkTalk says it will restrict calls that no more calls can be made on your landline. They say there may be a delay of a few hours in applying the restriction.
I've noticed that TalkTalk would send me an email to say i was close to exceeding the allowance but not restrict the line. In some cases, i have seen that TalkTalk have allowed calls to be made on the line for upto 21 days after the allowance had been reached.
Recently though, i've noticed that TalkTalk basically didn't apply any restriction to the line for months on end. At least 5 months even though the monthly allowance had been reached at least a week before my billing date, sometimes 3 weeks before. This has meant that my bills have been higher.
Anyone else had a similar issue or have any advice? I know some will say just go with someone else which i will explore at the end of my contract. However, in the meantime, it seems unreasonable for TalkTalk to advertise something it just does not implement.
