impatient, rude staff

My complaint is not so much about the product or company as it is about the staff, i spoke to someone at faithful to nature on Monday that was speaking over me and so rude and i let it slide but it happened again today, could it be the culture at the company or is it one person? I have been such a supporter of faithful to nature and they have been really on the ball with great service till the last two times. Both are based on late deliveries and when i contact them they are rude and impatient, I never said that they are to blame for dawnwing's delays. Faithful to nature say on their website that they value their customers feedback, and i would like to believe that my feedback counts, so when i tell them that dawnwing is slacking and damaging their reputation, it should be noted, the staff rather become impatient, speak over me and rush me of the phone. My frustration is that i ordered a plant and its been in a box for so long now (since 29 Nov 2017). Than you get answered as if they are doing you a favor: "Well if there is something wrong just send it back and we will send you another one". Staff should really understand their position as customer satisfaction agents, this plant was bought for my anniversary which has passed now and also no matter what my reason is don't don't shoot it down. Than again faithful to nature have customer satisfaction ninjas and that's how you treated me. The point is i ordered online due to fast efficient seamless service not making work for myself, this exercise has clearly turned into serious admin.
