Siri - phoenetic name issues

Question

I’ve been trying to get Siri to differentiate between my wife’s name, “Bec” and my banks name “B.E.C.U.”. However, every time I ask Siri to “call Bec”, it dials the bank and every time I ask Siri to call B.E.C.U., it puts up "Bec you" and directs me to my wife's contact info. This VERY frustrating.
I’ve tried to add a pronunciation in the phonetic pronunciation field but nothing seems to work. I put in “Beck” for Bec and “be-ee-see-you” and "B. E. C. U." for the bank. I also tried to change the banks name to "Bank BECU" but I get exactly the same results. Every once in a while Siri thinks I say "back" and directs me to local hotels (which doesn't make sense). Even if I ask Siri to call “my wife”, she asks for her name and I get the same result as above. 
How can I fix this?

Answer 1

Is you carrier Verizon?  If so, try this:
Open the phone and dial *228. This is a Verizon over-the-air programming number.
When the system answer press 1 for "Program or activate your phone"
Wait for the call to disconnect. You should get a prompt stating "Settings updated."
Double tap the Home button to bring up the recently used apps list at the bottom.  Locate the Phone, Message, and Contacts apps, swiping if necessary, and press and hold until they jiggle then press the red minus sign to stop them.
Wait a 3-5 minutes.
Open the Contacts App to see if they're fixed.
