We decided to switch from another company to SBIS Reporting. The accountant requested an invoice, which was issued, but the promised discount for switching was not provided. It could have been up to 80%. We contacted SBIS three times: the first time we received an invoice without a discount, the second time they requested documents to obtain the discount, and then the manager disappeared. The third time, another manager called back, stating that it was unacceptable not to have a response, and promised to resolve the issue within a few days. I sent the documents again, and he disappeared once more! About 10 days later, he reappeared, apologized, saying he had been ill, and then vanished again. I wrote to them myself — in response, I got: "Did no one call you back? You are not entitled to a discount since the invoice has already been issued without a discount." It's absurd! Almost a month of this kind of "communication."
