Tithing help asap

I am trying to pay tithing online, and help pay for my brother in laws mission he's in a different ward it was working at the start of the year but the last month I get a no reply email saying authority cancelled. I have asked my ward clerk he said talk to the bank. I called my bank they say talk to ur Church. I just want to pay my tithing and brother in law mission

The next step would be to have your ward clerk contact the service center for assistance. If he doesn't know how to contact them, he can start at https://www.churchofjesuschrist.org/help/support/record-keeping/finance/contact-information.
