Complete waste of time & money

I had this treatment done at a local salon and I would have got better results just brushing my teeth. I felt like an idiot sitting around with gumshield in my mouth for 20 minutes then afterwards I had to spit in a bag, this was in front of everyone else in the busy salon. There was hardly any difference afterwards and no difference the next morning so i went to complain and they told me i have to contact the company as its technically a product. They told me they dont do refunds and hung up. I searched for Megawhite online and on the first page of google you can see that they have been proseucted for illegal teeth whitening and are run by a fraudster from Scotland called Bryan Christie. Worried about my teeth now. If you are thinking about this then run the other way
