New IG Vinyl pool with surface cracks and loose handrail????

[webfeet]

The cracks are hairline cracks- very small- a fingernail file will not even fit in them. However, there are several of them.

Yes, the pvc was pulled out. It looks like there are galvanized sleeves that the rails sit in. PB says that since we want a safety cover, the handrail could not be cemented into the deck. That is why it is loose. Supposedly we can take the handrail off. He says it is too late to make it tight and claims that he told us this before he started the pool. We don't recall the conversation. Can the handrail be stabilized at this point, without tearing up the deck? He says no, that he can only try to put wedges in, to tighten it up some.
