Do their "Customer promise/guarantees" cover changes in eye/prescription? If within the 3-month time-frame?

Multifocal glasses give you clear vision at all distances, with no tell-tale lines. But because we understand that some people take a bit of time to get used to them, we’re giving you an additional guarantee. If you can’t get on with them, bring them back within three months of the date of your purchase and you can exchange them for either a pair of bifocals or two pairs of single vision glasses (one for reading and one for distance) and we’ll refund any price difference.
Update:
It's for younger sis who's Rx has been changing/getting worse seems often.
Optom. knows about it from previous tests, but we didn't get to purchase due to finance reasons. We however did purchase from Clearly Online a couple times with new SS scripts, but she always had problems with them, or would seem to develop changes in vision after around 2 months more or less (she'd say the glasses make her vision blurry).
So it seems local Specsavers is the way to go (even if more exxy) to help monitor her deterioration.
Planning to get tested again soon and buy it there.
What did the place you bought the glasses from say when you called them?
