I collected my own long ago. However, as brother Usman hinted, some people still didn't collect their own. May be because their temporary cards are lost or they are no more reside in those areas where they registered. Some are even died.If you lost your temporary slip, there's nothing to worry about, just look for someone whom you registered along side in the same polling station and check his/ her PU No. at the top right corner of the slip. Take that number to the Local Gov't INEC office they will check yours using that PU number. Hurry up!
