I have been a member of FirstMark Credit Union since 1971 when I first started teaching. It was then called San Antonio Teachers’ Credit Union. I have never had another credit union or bank even though I’ve been asked about joining another big credit union in San Antonio.
You have always taken care of me whether it was my several accounts or issues I had. Always there and always supportive.

Horrible Online banking

I’ve had the WORST experience with Firstmark CU online website and mobile app. Since I only use FCU for my auto loan, I only have the minimum $5 in an account. However, the only way to make an online auto loan payment is to deposit money in that $5 account. My issues.... there is no auto loan “make payment” online feature. Nor is there an online/mobile app feature to easily deposit money.

Phone Customer Support explained my options to make payment were to come in to bank, post office mail payment (who does those two anymore), call in and “talk” to support to make a payment or set up external account to deposit money in account.

It boggles my mind on how archaic their online features are. For me convenience is a must and for that reason, I am considering refinancing my auto loan with my credit union. I will be 50 this year. I’m in the older age group. So when I say (no offense) you have to be an older mature person to enjoy this Credit Union, I mean older person who probably still uses a flip phone or home phone still.

For now, I’m in the middle of setting up an external account. So far it’s been a normal “3 business day” process to verify accounts. I’m hoping this will help my online payment process.

Stay tuned..... I’ll give my rating on how long the process takes to deposit from my day-to-day bank to this CU.

Should there be other suggestions that will make my online auto pay convenient, DO TELL.

Debit card alerts

I’ve tried several times and even emailed the help desk on the debit card alerts I had to get a new debit card which someone was trying to buy items online. I canceled my card right away and got the new one, but the debit card alerts would not let me mark my alerts on the new card. I would be able to get to a certain point then it would say error. I emailed 3 times and it still does not work. The alert service has helped me with unknown purchases and I value that but can not register my new card.
