Disgusting. When trying to pay for the IMEI registration, the device notifies that the change will be credited to the account. But at the same time, if your bills require change, then he does not accept them, and asks you to deposit the exact amount. There is no way to cancel, there is no way to withdraw the money that has already been deposited. As a result, he will simply eat what you have contributed. A great way to withdraw money.
