At Tennsa ("we", "us", or "our") we want you to know exactly what you are buying before you pay for it. That is why every customer gets a full 30-day free trial with no credit card required, and it is why we do not operate a money-back guarantee after purchase.
Please read this policy carefully before subscribing.
Tennsa OS comes with a 30-day free trial. No credit card is required to start it. During the trial you get:
The trial exists so that you can reach a confident decision without paying us anything. You can connect your real systems and see real output from your own data before any money changes hands.
Because you can fully evaluate Tennsa OS at no cost and no risk, we do not offer a money-back guarantee once a subscription has been paid for. We would rather you take the full 30 days and be certain than pay first and ask for it back. If the trial has not given you what you needed to decide, write to us at info@tennsa.com before you subscribe and we will help.
Tennsa OS is billed monthly. You may cancel at any time - there is no minimum term and no cancellation penalty.
Tennsa OS is a digital service delivered over the internet and made available to you immediately on subscribing. Because the 30-day free trial lets you evaluate the entire product at no cost, subscription payments are not refundable.
This means:
The one exception is a billing error on our side, set out in section 5 below.
Your statutory rights: nothing in this policy is intended to limit or remove any right you have under South African consumer law, including the Consumer Protection Act and the Electronic Communications and Transactions Act. Where this policy conflicts with a right the law gives you, the law applies.
If a technical problem or a defect in our software stops Tennsa OS working for you, tell us at info@tennsa.com. We would rather hear about it early than have you sit with it.
We treat problems that stop you using the product as our first priority, and we will keep you updated while we work on it. If something serious cannot be resolved, we will deal with your situation individually and in good faith rather than applying a blanket rule - and your rights under South African consumer law, set out in section 3, are unaffected either way.
If you believe you have been charged in error - for example a duplicate charge, a charge after cancellation, or a charge for the wrong amount - contact us and we will investigate and correct it.
To raise a billing-error refund request, please email us at info@tennsa.com with the following details:
We will review your request and notify you of the outcome within 7 business days. If approved, your refund will be processed, and a credit will automatically be applied to your original method of payment (via Paystack) within 5-10 business days.
We reserve the right to modify this Refund Policy at any time. Changes and clarifications will take effect immediately upon their posting on the website.
