ABC News' Alexandra Ludka and Suzan Clarke report:

A tweet by pop star Justin Bieber has a Texas woman wishing for the singer's apology.

Bieber tweeted an invitation for followers to "call me right now" along with a telephone number that had a question mark in place of the missing final digit.

Of course, that didn't stop the tween idol's enterprising fans, 19 million of whom follow him on Twitter.  Many of them filled in the blank and ended up reaching 88-year-old Dilcie Fleming of Dallas.

In an interview with ABC News Wednesday, Fleming said she's been inundated with calls from fans seeking to talk Bieber.

"I had no idea what was going on," Fleming said. "I was told that this young man put a number up on the tweeter, or whatever it's called, but left off the last digit. People were punching in until they got an answer."

It got so bad that Fleming said she had to remove her phone from her bedroom.

"You kind of get upset and frustrated, you know," she said. "It's just a constant thing. I feel so sorry for these young girls. I may have been out of line but I told one of them girls I talked to, 'He doesn't care about you. You're just making money for him.'"

The pressure created by the March 7 tweet has eased somewhat, but Fleming said she still gets many hang-up calls. She has changed her recorded message to indicate that her number does not belong to Bieber.

Fleming consulted an attorney, but told ABC News that she has no plans to sue, as was reported earlier by other media outlets.

She called the attorney to ask for help in reaching Bieber, she said.

"I'd just like to have an apology in writing," Fleming added.

She'll also take concert tickets.

"I have grandchildren - and a 6-year-old great-granddaughter," she said.

Asked if she planned to change her phone number, Fleming responded with an emphatic negative.

"I've had this number since 1966 and I'm not about to change it," she said. "I think if this young man would put out that this was an error and he apologized, maybe people would quit calling."

Fleming isn't the only recipient of calls intended for Bieber. At least one other area resident has gotten calls from the fans known as Beliebers.

One man told CBSDFW.com that he still gets calls around the clock.

"Recently, I'm even getting calls from India. They want Justin Bieber to come to India," he said.
