Massively overcharged every month £100's

[AshleyK]

So, around 6 months ago I moved into a rural area without a phone line. I decided to get a 3g wifi sim for 30g to use with a huewei dongle. When setting up in store I was given (without my knowledge) a business contract which is uncapped. There is no way in the world I could possibly go over every month and be charged some months £400 plus for a £25 contract. I've ruled out all possibilities for going over the set amount, e.g changing passwords, disconnecting when not at home, hiding the thing. Even when I called costomer services last month they said I had 7g left to use within 2 days which i didnt use at all and have still recieved a £244 bill. I use my phone more than the dongle which i only have 5g on and I never go over. ive been with o2 for 10 years plus but if this doesnt get resolved there is no way in the world I will use or recomened their services ever again. In 6 months I have been charged over £1200 with no one able to give me an explenation as to why... help??

@Anonymous I am no longer a business customer so cannot comment on the revised business myo2 site . But it will show which days and how much data used .

@AshleyK I hope you get the required info you require to decipher what days have caused the overusage etc .

I'd disconnect the laptop completely, turn off its wifi and use the dongle stand alone in a phone's usb adaptor 3 pin plug something outputting .5 or .1 amp . Then get a wifi tablet for going on line.

 Or get a phone line.

Other options would be to get out of the business contract with o2 if you can but I'm guessing there might be penalties.

Or get a capped tablet data only sim from someone else and use that in the dongle assuming its unlocked and use the 02 SIM in a phone or tablet where you can more easily control the data usage and keep within the limits.

Or just put the sim in a draw and pay the £25 / month till you can cancel.
