Poor customer service, Tukwila, Washington store

Today i went to the store to get helped transfering my phone number to a new phone that i just purchased unlocked, the guy that "help me" was all the time with a bad attitude i explain to him the situation that i couldn't do it in the mobile app  because it was saying the phone was locked when its not he proceed to tell me that the phone is locked that I have to go to the store i purchased ir for them to unlocked which i proceeded to tell him that the phone inded was not locked he looked at me like i was lying he told me to leave not to waste his time i went to the place i bought it, and they told me it  was not locked which i already knew such a waste of time, so i try getting helped on the chat live on xfinity app and i was able to finally transfer it how come they could help but in the actually store they couldn't what a shame please get those guys well trained, they were all in their phones doing nothing they should be training for situations like this not doing nothing and being rude when kindly asked for helped. Definitely not going back to that store again, will continue with live chat Definitely more helpful and comprehensive.
