Interakt ‑ Sell on WhatsApp

Extremely disappointing experience with Interakt.
Our WhatsApp marketing automations suddenly stopped working because our subscription was automatically deactivated without any warning, even though we were already on a paid Growth plan (~$41).
To make matters worse, the platform then showed two different subscriptions on the same account:

Growth Plan under Sell on WhatsApp
Starter Plan under WhatsApp Marketing

Because the marketing channel had stopped functioning entirely, we were forced to subscribe again just to restore basic functionality, meaning we are now being double billed for something that should be a single service.
We raised a support ticket immediately.
It has now been several days with no resolution. The only response we received was:
"We are checking internally."

Meanwhile:
Our automations stopped working
Our WhatsApp marketing campaigns were disrupted
Our billing is incorrect
And there is no urgency from the support team

For a platform that positions itself as a critical business tool, this level of support is unacceptable.
When a company’s marketing infrastructure breaks, days of delay is not acceptable.
If this issue is not resolved immediately and the billing corrected, we will be moving our business to another platform.
Right now, based on this experience, I cannot recommend Interakt to any serious Shopify brand.
