ATT telecommunications AT&T phone sold me VOIP I didn't need and then charged me restocking fee for return Westminster, California

On November 11, 2012  I ordered a bundled service for Direct TV , phone, and service for my home (((REDACTED))) in
Cypress,California.   I upgraded my AT&T internet and subsequently, my AT&T telephone landline was cut off.  After many calls to operators, technicians, even driving to the retail AT&Tstore in Westminster, California  for further help.  I explained to every agent, technician that my landline was not to be turned off.  It took eight days to make my situation understood. By this time I had purchased a VOIP apparatus for a dead landline.

Waiting three days, on the 27th of November I had gone through all the repair numbers at AT&T for repairs/technician and in desperation I drove up to the retail store in Westminster, California and told the manager my problem and waited in line for a salesperson Gabe to assist me further .  Gabe took a look at the paperwork from At&T/Direct TV and I explained that I wanted my landline connected.

However, (though selective hearing is problematic at the store) he offered me afree apparatus for use:  a  VOIP system.  
The wireless VOIP performed poorly as I was unable to connect to my neighbors home in Cypress nor to make calls in a normal fashion. 

Further, Gabe asked me for my social security number and entered it into an AT&T database and said  the VOIP was now ($10.07) ten dollars and seven cents ! Why does AT&T need this information if the customer pays in cash? I paid cash and throught this procedure strange  (more disappointing was a complete loss of time and having to drive back - return it) .  I was charged with a restocking fee of twenty four dollars and ninety-three cents ($24.93).  Gabe later said it wasnt for a restocking fee but that it was a tax assessment! 

I am dismayed with the lack of  ethics from AT&T  employees.

I would like to have my money back for having been sold an unnecessary device.

Having used public utilities services here in California for the past forty-five years, this is a new low  level  of 
downgrading services for the public at large.
