OK, i took some advice here on HUKD a few month ago. I was after using broadband with my laptop when i was away with work on a course.
I bought a 3 dongle with 1gb of credit and got cashback from quidco; all good so far!
I requested another sim from 3 and fitted that sim into my dongle when the first sims 1gb expired after 1 month. I topped up my account with £10, used a bolt on and purchased unlimited mobile browsing for 1 month for £5.
All went smoothly; however, 1 week later, it says my top up has expired and it ate into £1.10 of my remaining credit!!!
What went wrong people?!
