Order Return

We bought 3 Mattress from CIELO during the black Friday sale in November. The Mattress were only delivered 10 January 2020. We were patient with CIELO and we waited for the Mattress without complaining. This was about a month and half of waiting. On the 27 January we informed customer service that the Mattress was too big for out bed and we wanted an exchange. However we were told that the 14 days has passed and we cannot be assisted. If they took so long to deliver I do not understand why the Mattress we got on 10th January cannot be returned. This process seems biased as the website indicated that the delivery takes takes approximately 5-10 days to occur, but our delivery time frames where way too long compared to the 5-10 days that was stipulated. We even understood when the other Mattress was delivered dirty and it had to be returned. And also our patio-set had some defects and we only got the final order on the 23rd January which was about 2 month from the order date. Please have a look at our issue and assist.
