Does a sent text message constitute confirmation that a parking session has been paid?

A proof of parking permit purchase is not a text message sent by the customer, but a text message received by the customer, which informs him or her that the permit has been successfully purchased. If the customer does not receive a return text message within 2 minutes, it shall be considered that the purchase has failed and the customer shall be obligated to use some other parking payment method. A proof of purchase contains the registration plate number, which enables the customer to once again verify the entered data and correct any possible mistakes.
