Most pathetic service that I ever recieved

Went to post office on the 23rd of February 2022 to renew licence disc that expires on 28th of February. Post office is offline and tell us to renew it online and will receive it via courier within 3 working days... its been a month.. Already paid all fees and courier fees included ,but no disc recieved yet. Phoned 4 times already , where they only tell you there was a system error and it will be delivered this week. (That was last week!) Monday I phoned ,they could pick up the payment on the system and everything, they will escalate it to IT department amd disc will be delivered during the week. Today! Friday! I phoned again... now they wanted copy of ID and proof of payment.. after forwarding it to them , no one answered the phone after trying to call them about 20 times! This is the most utterly pathetic service ever recieved. Monday grace period is over so they will then want to give fines... who can answer for this rediculous service??? I need help and answers as soon as possible
