Customers of Bank of America (NYSE: BOA) were out of luck for about four hours yesterday when a glitch in the company’s website cause the online banking service to shut down.

Bank of America, based in Charlotte, NC, did not give specifics about the problem, only citing a ‘temporary system’ error. The glitch only affected the consumer online banking services and not the bank’s ATM or branch services. The company said online users may still have trouble logging in as of today. Service did come back for customers about 5:15pm EST on Friday.

As the company is working to get more customers signed up for online account management, a web glitch like Friday’s could be bad news for both the bank and its customers. Customers get used to the convenience of access to banking services at home but when problems arise, doubts increase as well. Many consumers still shy away from high-tech banking and prefer the brick and mortar banking experience. However, in an effort to keep up with the competition, more banks are offering online incentives to entice customers to make the switch.

Bank of America, no stranger to customer service problems in the past, have many customers already disgruntled with the bank over the last few years. But while complaints are on the rise, it seems the company’s stock is staying steady. Bank of America is still pegged as one of the country’s top banking institutions.

It is not immediately known what the four hour glitch on the website will bring but doubts will likely remain about the reliability of Bank of America’s online banking services. Customers who have grown tired of the lack of service satisfaction may consider moving on to other financial institutions with stable online services and less fees for banking.
