Where to file complaints regarding misinformation from Satisfaction Department agents?

This weekend I spent about 2 hours with a CSR to add a 5th line to my account and get 2 new phones after a long discussion and a last price or 196.30 he advised me that there could be a 10$ For updates after not getting the phones at the right address they call me back to say I will lose 20$ credit because of address change I never did and now the price of 196 is 237 a month when I called back a rude CSR at the satisfaction juste told me it is what it is and to try and get the credit from the store when I deal everything over the phone with them …or just give back the phones without any consideration that is totally unacceptable and a poor customer service! I just want what was told to me supposedly because I was a good customer!!
