smoothie a day subscription

I have subscribed to the 30 day smoothie subscription via the App. I am very unhappy with the service received from the call centre agent. I called to query about the definition of a subscription according to Kuai as I was not able to able to use a whole week of the smoothies and enquired if i could be able to carry over the days and I was informed it is not possible. The question I then asked is that the terms and conditions actually describe that you will not be able to carry the unused vouchers into the new subscription and this to me meant that I would not be able to take the unused vouchers into the new month. I discussed this with the agent when I called and told her that I am not happy with their description and they should be clearer on what the subscription speaks to. she indicated that she will escalate my issue and give feedback on the escalation, am still waiting for a call or some sort of email. Outside of anyone actually calling me there is still the audacity to bill an unhappy customer. I emailed 12 hours after the auto billing went off to tell them they have to cancel this and refund me because i am not happy with the service I am receiving, and I was told refunds are not possible as the auto reorder is loaded for my convenience. The challenge now it that it is not convenient for you to call an unhappy customer and resolve issues, but it is convenient to bill an unhappy customer. The terms and conditions also indicate I can cancel at any time with no other clauses indicated. If I have not even used one smoothing in my new month, why is it difficult to refund me. The app refers to checking the terms and condition on the website, but I didn’t find any terms and conditions pertaining to the APP smoothie a day subscription. Is this another trick to just get us confused and hopeless with issue resolution?
