VOXI mobile data not working.

[tvedtem]

So here is the situation.

I bought a VOXI PAYG SIM card from the Vodafone shop in Epsom around Christmas time.
I'm back in the UK now (September) and topped it up with 10 GBP, here

This worked for phone calls and SMS but I don't have working mobile internet.

Now, on asking VOXI.co.uk for support, it transpires that this number (even though I have a working SIM) is registered to someone else(!) and they refuse to help.
They referred me to the Vodafone shop, where I've just been, and the guy there refused to help also, because it is VOXI.
You may remember from earlier that this is the shop that sold me the SIM card in the first place...

He asked me to call 191, whereupon it asks for my mobile number and then plays me an automated message to talk to VOXI and promptly hangs up.

Apart from losing a couple of hours of my life which I will not get back, I would really appreciate some help here!
