Second degree burn from "VEET" hair removal product. Help?

i used veet in shower cream, the one with the sponge, when i came to use it i felt a really painful sting, when washing the cream off the water was extremely painful against my leg then found a MASSIVE rash and was in pain for most the night.
when ringing to complain i had to go through a 10 minute questionaire over the phone where i was asked ridiculous questions, when i asked what would happen if there was a fault in the product i got the response of “well i dont know, it would have to be discussed between me and my manager as we haven’t had a complaint about veet products before” what a load of bullpoo to be honest i wouldn’t recommend veet products to anyone, unless you are willing to have a bad reaction and be in pain for the next week!!!
