i used to work in the redemptions department for carphone warehouse and also a sister company called e2save. carphone warehouse because after a while they took away the time limit in which you had to claim, you eventually did get your money however with e2save it was a scam. you had to send in your 4th bill, it stated just that in the terms and conditions, your 4th bill. however say for example you took your contract on the 31st jan, e2save still count that day as a month, therefore would want the march bill, even tho you obviously would never hav recieved a bill in jan. you needed to get this in within 30 days of recieveing your bill...which obviously by the time you waited on ur actual 4 th bill thinkin it was april you had missed ur chance. it also depended on your network provider which way they issued the bills. i used to spend my whole 8 hours arguing that it wasnt a scam and you should have read the ts and cs as there was a table showing the bills needed to be sent in. however it was very misleading and was a scam! o how i enjoyed that job!!!
as someone said your better taking contracts directly from the networks!
