That is not the way I interpreted that paragraph, although the terms certainly could have changed since then, since I did not see that paragraph in my contract.Yes they all can till there is a price increase and lose nothing. And that new price will become the guaranteed price for the remainder of the contract unless you switch after another price increase again.
Example - you switch after a price increase of $3 to another package. You will pay not the full package price but $10 less than the package price, which would be $3 more than before.
Flex Pack is not specifically mentioned. Even if there were any "contrary terms," the word "Notwithstanding" automatically voids the contrary terms or conditions.Flex pack was not part of the $10 promotion, try looking in other parts of the contract to see if it discusses Flex Pack, possibly the "Contrary Terms"
If you switch to a qualifying Top package you will automatically start receiving the $10 discount for the rest of the contract.
I think my interpretation of the additional $120 in credits is probably correct. If there is a $5 per month increase six months into the contract, the price protection would mean a discount of $5 per month for the next 12 months, followed by another $5 per month increase in month 18, which means the price protection would give a $10 per month discount for the final six months of the contract. ($5 times 12 + $10 times 6 = $120) If the price increases start sooner than six months into the contract, or if the price increases are greater than expected, then the total discount would be greater than $120. This discount, added to the guaranteed $120 with autopay ($5 times 24) would be the "aggregate value of $240 or more."
