A complete and brazen scam. For this, there should actually be punishment. They deduct money for sending SMS. Meanwhile, on the website in the personal account, the status of the SMS sending says "delivered." But it turned out that not a single SMS actually reached our counterparts. Our company conducted mass advertising mailings through this site for several months. Only now did we realize that the SMS did not reach the counterparts at all.
We wrote a request to this company, and they replied that we were the fools because we needed some kind of contract that they did not receive. Initially, there is electronic registration on the website, and you can top up the balance of your personal account online. They do this without a contract. They allow sending mailings without a contract. They allow deducting money for their benefit without a contract. But to actually deliver the SMS to the counterparts, they had an excuse, saying that a certain contract was needed.
What kind of scam is this? People, don't be fooled. Our lawyer is currently preparing a complaint, which will be sent to them. Next, we will file a lawsuit.
