Reputable nail techs won't touch anyone else's work because we don't know what products have been used as previously stated by other posters.
You can either wait and get her to remove, or remove yourself if builder in a bottle, or soft gel.
For removal: Take a 100grit file and buff down to a thin base layer, put a bowl of acetone in a bowl of hot water, and soak for around 10 minutes then scrape off the gel, use a wooden manicure stick (Amazon) being extra careful not to damage the nail plate.
If it's a hard gel, these have to be filed off. And I probably wouldn't attempt to remove by yourself as you'll end up with nails as thin as paper and very fragile, susceptible to breakage etc.
Or, you can attempt to fix them using a 180 grit file, buff over the nail focusing on the lumpy top bits until they resemble a nail shape whilst you wait for a removal, but tell the tech you'll be doing this due to finding them uncomfortable and still expect removal to be covered.
Please don't try and do your own nails with gel/acrylic. These items shouldn't be sold to non professionals because of the chemicals involved. And reputable brands that are less likely to cause issues will ask for qualifications before sale. Amazon/temu kits usually contain MMA and these are responsible for the majority of acquired acetate allergies. There is a high risk of over exposure to the chemicals in the gels, it's not just long lasting polish.
If the nail product touches the skin, your body can produce an immune response and this is not something you want. Allergies to acetate means you won't be able to have dental implants or hip replacements in the future.
Hope this helps OP. They are awful tbf. 💕
