DEATHWATCH: Samba Mobile shuts up shop
Samba, of course, offered free broadband to customers who bought one of their Sims, which could be used in your phone and tablet. Once you'd eaten your data allowance, you could access the free internet connection if you were willing to watch some adverts.
The reason that the company have ceased trading isn't anything to do with going into administration, but rather, the rising cost of wholesale data is too much for them.
Now what's all this about a refund?
Well, if you got your Samba Sim card this month, you should get an automatic refund to your PayPal account which you used to buy it. If you got one before April 2014, then Samba won't be giving a refund. If you want to dispute that, you'll have to take it up with PayPal. In that case, you may as well try and punch the sun.
If you're adamant you want reimbursing, then PayPal disputes must be taken up within 45 days of your initial purchase. As Samba didn't sell anything over £100, Chargeback or Section 75 of the Consumer Credit Act doesn't apply here.
If you have credit left, you should be refunded the amount automatically. You won't be getting a refund for the cost of your dongle though, because that can still be used if you find a new provider for it. Again, if you have a problem with that, you'll have to file a dispute with PayPal.
If you want to know more about it, see Samba's website where there's further information.
