Futuretel replaced my 128gb phone with a 64gb one....

Futuretel replaced my 128gb phone with a 64gb one. They originally denied I sent a 128gb phone, stating that they upgraded me from 32gb to 64gb. After admitting their mistake they stated that I could keep the smaller phone or they could do is break my phone by putting in the non-working part if I sent them the phone again (yea right)
