Mobiles 4free rang my teenage daughter in June and told her if she switched her contract from O2 to 3, they would foot the bill for the remaining 9 months of the O2 contract. The new 3 contract had all sorts of extras to persuade her, so she set about persuading me (the idiot footing the bill). I rang mobiles4free as this deal seemed to good to be true (ha). Oh yes they said, we'll reimburse you for the O2 contract for the remaining 9 months, if you send us the proof that you've paid it. Guess what? Not a bean from them in 4 months. I contacted 3 who naturally claimed that mobiles4free were acting independently from them and more surprises, they now had no further dealings with them. No one answers at mobiles4free and now I'm paying 2 mobile phone contracts. Beware!
