Is there an analogy with smoking though ?
Perhaps if the cigarettes supplied had been filled with a lesser quality tobacco than had been claimed on the pack ?
In both cases (if proven) the customer would be perfectly entitled to claim their money back from the retailer. It would then be up to the retailer (in this case...clinic) to claim from the supplier/manufacturer.
The clinics are businesses, and as such are just as liable for miss-selling their products and services as any other business.
