Reducing Credit limit

[#1]

Hi,
is there a way to reduce my credit limit for my home phone? We have evenings and weekends package and it;s currently set at £55 Buffer, but i don;t want to go anywhere near that amount, ideally i'd like it set to £3-£5 maximum.
If it can be changed please advise how i do so as there is no option on the website that i can clearly see.
Many thanks!

You will need to call PN or use chat and request it to be lowered
kind regards

It's also worth bearing in mind that with low amounts around £3-£5 as you have said, it could be easy to run in to the limit. If the credit limit is hit and call barring is applied, a £5.76 call barring charge would be applicable.

Thanks guys!
Some good information there!
Would you not get a warning that you were close to using your buffer?
I don't plan on using it outside of the evening and weekend times to UK numbers only.

You should certainly get a warning email when you get close to the limit, however as call data isn't recorded in real time it could be easy to pass £3-£5 of calls before the email is actually triggered.
