worst experience in MW ever!

sometimes nobody answer ur call, but they will call back with block number after 2, or 3 hours. if u can't answer that call, they will keep calling back at least twice! at least twice with block number!! do not call me back!! fuck y! WTF, i hate MW running business in that way!! more worse is: i book hebe for today., (appointment is made 4 days before already) but today they just tell me she is day off without any excuse. i come for fun, not for wasteing my time. anyway, MW is almost same stupid level as BBF!
