Sealing around a bath with a big gap

[mezbones]

We had somebody in to put a brand new bath in our bathroom and basically the guy has left the bath moving too much as he hasn't fixed it properly to the wall. We have tried numerous times to seal around with silicone but it always fails in the corner where the movement is most. I have silicone bath tape as well but that comes off. I'd appreciate any help.

Thanks.

Is there something stopping you from fixing it to the wall now?

Also, are the feet screwed to the floor and the leg locknuts tightened?

Before you silicone around the bath, half fill it full of water n let the silicone go off before letting the water out, that way the seal will be under compession and less likely to fail
