Tesco Hudl 2 not switching on or charging

So, I had my Hudl 2 for about 2 months but my mother took it abroad for about 5 weeks. It ran out of charging on the first day after which they attempted to put it on charging but it was completely flat and not working. I thought it was because we used a different charger abroad so when we returned I put it back onto its original charger but it still didn't switch on. It has now been almost a month but it isn't switch on.

Is there a way to revive it or should we try and get it repaired?

Thank You
