They have a delivery service, so I asked can they deliver my pills. I send a whatsapp at 13:40 and asked that the deliver my pills. At 15:50 they said my pills will be delivered in the next half and uur. It is 17:30 and I am still waiting for my pills. The person working with the whatsapp is not one of the friendliest.
