Tesco text scam - any way to get tMobile to revise bill charge?

Lit_Up

I've just looked and my mum's mobile bills have been spiked by up to 20 quid a month recently. She has been receiving texts from 700034065. It's a scam, googling this number shows up a page which says: Tesco voucher draw scam
It is very easy to be conned by this scam as it looks as though it is a genuine contact from Tesco. This number is linked to text messages requesting a text reply which it is stated is free whereas in fact £1.50 is deducted from your mobile account for each 'free' reply text sent. Further if the text sender is not stopped they will continue to take £4.50 every week from your targeted mobile account .

Is there anyway to get the money back? TMobile should block this scam at the network level, not leave their users vulnerable to fraud.
