DIRECT TV VISA GiIFT CARD SCAM

When I signed up for direct tv I was promised a $100.00 gift card..  I was not told that there was an expiration date.  When I received the card I activated it and put it away until I was going to make a large purchase.  I didn't review the card other than to look at the card number.

I was told by the Direct TV salesman that I could use it at any time.  When I activated it there was no mention of an expiration date............................

When I tried to use it I was told by the store that it had expired.

I signed up for Direct TV because of the incentives now I am getting screwed over by the company. I have tried in the past to be reissued another $100.00 gift card but every time I call someone in customer service I get put on hold forever, passed along to to multiple people whose English is very hard to understand or just get hung up on. 

I pay my AT&T bill on time and have been a loyal customer you would think a Company such as  AT&T would be loyal to their customers.  You know they are aware of how badly they run their customers around in circles when they call call customer service with a problem such as this.  I'm sure that if I tried to cancel my service they would charge me the cancellation fee.
