Duplicate accounts

I have 2 accounts, one is associated with my MRN, but the one I have been paying tithing on for over a year does not recognize me as a member. Is there a way consolidate my accounts so my donations show on my membership account? If I can't do this on my own, who do I contact and what is their contact information?

Please see this thread/topic for an answer to basically the same question:

Thanks, I was on there looking for topics and overlooked that.
