English + swiss accent

I called the Kreis buro office to get info about some things. The women on the phone was asking for a reference number and she was saying something about giving the first three letters of the family name. I start spelling, she starts yelling "no no, I need the number" and then I ask her kindly to repeat which number she is looking for because couldn't understand the humming.

Her response: You either learn German or English and call back, or just find someone to speak for you.

There goes my faith in swiss kindness.
