radio shack False advertising Bellingham Washington

Went in my local radio shack before christmas was looking at a boost phone  a warp 4g was on sale for 99.99 unfortunatly they were out at that time.  went back into the store today 12/27/2013  phone was still on sale  ask the assoicate if they had any he went the back room came back with one.  rang it up came too 143 and change  i told him  the display says 99.99 he went over took a look grabbed the diplay tag told me the sale was over and there is nothing that can be done.   i told him no thanks and left the store.   went back a short tiem later to talk to a manager   spoke again to matt  who informed that the manger just left and no one could help me  i asked who was in charge  he replied no one   but if i had a complaint i was welcome to call the buisness office  and he handed me a card  i left the store called the office and started to explain i got interupted by matt who again told me there is nothing i could do for me and there was no manger there   (so why give me the card and tell me to call)   this is not the first time at this store
