Cricket Cricket Wireless lying/poor business practicies/ rip off el paso Nationwide

Bought new cell phone from cricket in June 2014, Samsung s4, total cost $650.00...well since they merged a couple of week after that now the phone will no longer work under them because they are now AT&T...at store told by sales rep too bad and added that they had the right to suspend service with the phone without notice ALL CUSTOMERS IN CRICKET NETWORK SHOULD BE THANKFUL THAT THEY DID NOT JUST DISCONNECT THEM FROM ONE DAY TO ANOTHER... SHE WAS VERY RUDE AND EVEN HAD THE NERVE TO SAY NO OTHER COMPANY COULD COMPETE WITH CRICKETS PRICE..... LOCATION OF THE CRICKET STORE 4001 DYER EL PASO TEXAS 79930 PHONE NUMBER 915 564-0005.  The sales associate was not sympathetic of the dilema a little understanding would have helped...even though she could not do anything about it....sympathizing with customer...is part of customer service... needless to say I HATE Cricket and would not give one more cent to buying a phone or paying one month of cricket service even if it was the cheapest in the world.  THEY MIGHT THINK IT IS THE CHEAPEST WIRELESS SERVICE...BUT EVEN IF THAT WAS THE CASE, AND IT IS NOT....THEY DO NOT DESERVE MY MONEY AND I WILL NOT CONTINUE WITH THEM...THE REASON THEY DECEIVE CUSTOMERS AND HAVE VERY VERY POOR CUSTOMER SERVICE!!!
