If the parcel arrives visibly damaged, you can refuse delivery and tell the courier why. If you accept it and discover damage later, or if a component is missing, let us know as soon as possible at info@vivabioma.com. Photographs are helpful but not essential.
We will send you a replacement kit free of charge or, if you prefer, refund your payment. Do not use a damaged kit or a tube that has lost its stabilising solution, as the sample may be unsuitable.
