Send it back and make the manufacturer fix it. If they're "reputable" they will.

This is a manufacturing defect; they should replaced the mold for you. Call your supplier and then the maker if necessary.

FWIW-Off center sprue holes don't seem to cause too many problems, in fact they can be a help in some situations. Your issue may be related to venting. I'd suggest reading the stickies of "leementing". Simply chasing the vent lines and very, very lightly breaking the top edge of the moulds halves can help enormously, but you ahve to proceed very carefully. This is no place to "get a bigger hammer"!!!
