It is not our job to ask on why you are unable to login to iCloud because they reasons may vary. Regardless of that, the fact that you are unable to access iCloud is really a major problem.
But do not despair. At this point, several methods were developed and can be practically used to help you overcome this issue. Probably the easiest way to deal with this problem is to use Apple’s services. In order to do so just go to the nearest Apple store and bring the original receipt of the iPhone (this is the case because you must provide ownership proof). After a day or two the iCloud lock will be removed. However, keep in mind that this can be quite costly and you should always reconsider whether this is the best solution.
