AT+T UNIVERSAL CARD

As this card is discontinuing the 30 minutes of free calling time will you offer me a benefit of equal value?  I have been a perfect customer using this card for DECADES since it was first issued and the only reason I use it is for to take advantage of the 30 minute calling benefit.  If you do not continue to offer me the 30 minute calling  benefit or an equal benefit I will cancel this card as it is of no benefit to me.
