order confirmation and email confirmation not have same information?!?

[strawberry2]

I just place an order online, I don't know why the order confirmation email does not have the same information as the original order confirmation.  

After I hit the button to place the order, the order confirmation page clearly showed:
-  the installation appt on July 23, 2015 8:00 AM - 9:00 AM in green color
-  the order summary include "$350 Visa prepaid card" in green color
-  the estimate bill is 154.92

But in the email confirmation, it provided  total different thing:
- no where on the email order confirmation  said about $350 Visa prepaid card.
- the installation appt somehow change to July 28, 2015 8:00AM - 5:00 PM (<- move to 5 days later with an 8 hours window to expect people to take whole day off  from work to get installation?)
- the estimate bill become 241.22 (<- move up 86.3)

Does the email confirmation have the wrong information or Is it normal that Verizon automatically make change to the order after it submitted? Bill increase, date install change and no more prepaid card?

Note the bill estimate on the email may have certain extra charges, hopefully all correct.  You will need to check when you get actual bill.  Things like install fee (if not waived) and partial month charges.  I don't remember if other taxes and fees are also included on one but not the other.
