Sprint Double billing , Unauthorized plans ,rude unknowlageable employees , No idea how to conduct business all, Florida

 I have been a customer of Sprint for years and finally decided to consolidate my landlines onto Sprint devices, to alleiviate unaffordable phone bills.  So I had  Sprint port my phones onto 1 Sprint device and 1 Nextel device ( for upstate NY coverage).   The Nextel device not only was of the poorest quality but it took me 2 weeks of phone calls to technicians and sprint support to get the darn thing working. Meanwhile they were chargeing me for 3 cell phones, extra data uasge and  an ols card for the computer , 2 new devices and activation fees.  The bill has climed to over $300 by January . (this all started in December)   By february they decided that they would double bill me for everything and change all my plans without my authorization and not acknowlage me or my complaints or at the very least they could credit my account .  After several hours on the phone I still got no where with these idiots after being transfered to different depts. and supervisors and certified letters I had to take 2  ,   eight hour work days off to travel to 2 Sprint stores to rectify my bill and show them that I did not authorize these plans and that they were double billing me.   I spoke to the financial dept and got a credit of $130  after spending 9 hours on the phone with him explaining the bill.  All this and still I get abill now for over $600.   This is there idea of what I owe them.  I signed only for the 700 plan for the amount of $69.99 a month plus the usb hub for $ 59.99 a month which was supposed to be  a free upgrade  and I am supposed to recieve a IBM employee discount of %25 .  I know I have not gone into every detail of my horrific nightmare I have had to endure since December but this should give a brief overview of my Valid complaints  and  facts .  I have saved every copy of the invoices that I signed only plus I have copies of certified mail .etc......
