But he bought it from the same company, u are just a different contact person, u still represent the same lab which he purchased it from, if i order something somewhere and i get a different contact person when i have a complient , they wont say sorry it was a different person ur complient is not valid anymore, do u see ur logic here?
imagine if a customer has a complient after a month from now, and the company gets a different seller here, u were fired or leave or whatever, would his complient also still be not valid because its a different seller/contact person now???
