What happens if I could not pay first bill of O2 for 24 month contract and there on .
What is the Importance or connection with first bill being paid . Is there any importance of first bill to be paid as I saw lot of services are enabled only after first bill is paid .
I was assigned 2 new connections when I requested for a IPHONE MOBILE hardware . I already own 1 For customer number: xxxxxxx65 contract with O2 for 24 months what should I do to with the 2 new 24 months contracts For customer number: xxxxxx97 that O2 has assigned me .
I do not have money and cannot affort to pay for 3 (For customer number: xxxxxx97, For customer number: xxxxxx65) O2 contracts for 24 months and each time I request an IPHONE or any hardware the request is getting rejected . this is how the 2 new connections got assigned to me .
