Unhappy client because of the dishonesty displayed by Maison Niche essentials

I bought perfume from Niche essential and i was dissapointed to find that it didnt leave any sent on me so i sent them an email, they made a promise to send me another bottle with the return of the one i have bought and we had an agreement so i have been waiting now they seem to ignore me because i sent an email and they havent rep**** since last month. When i checked their website they ask customers to leave reviews because the old ones got deleted when they updated their system i found that to be very odd.
