Unemployment issue

I applied for unemployment because I was laid off from safeway. I put the wrong employer on the application, I assumed it was Albertsons because they do own safeway but NAI Saturn eastern LLC was my employer. Somebody from unemployment called me on the 29th of November and I couldn’t understand the voicemail she left so I called the local office three times that same day to find out who called and why, each time their system was down. I called back on the 30th and whoever I talked to said “everything was fine”. I believed her and dropped it. Days later I got a letter stating that I was denied because I “failed to contact the local office Within 48 hours”. I appealed, at the appeal hearing I explained the whole situation although I did not have phone records to prove that I did call. The unemployment representative then said that “I did not call the ‘proper’ phone number.”... I was denied again. Now I have a board appeal and I printed out the phone records that prove I did call within 48 hours. Does anyone have advice? Should I bring any more proof?
