Fixed Fiamma awning -help on how to remove please

Hi anyone who can help on this please: we have bought a used caravan which has had a brand new fixed Fiamma F45s Titanium 300 canopy fitted. As we would prefer a conventional awning to accommodate family, we are considering having the Fiamma removed -does anyone have any experience of this? We are worried about making the fixing holes 'good' and look ok afterwards? Also any idea of cost? Any comments gratefully appreciated,  cheers David
