Transfer banned for 24 hours constantly

When i first started the game, it ran smoothly with accessing the transfer market, selling and buying ect. Then one day i got banned for 24 hours from selling players and its been 4 weeks now. Ive gone on ea help 6 times and i get told its a bug/ an issue thats gonna be solved….. i can buy players but anything else is either a connection issue message appears or a bid/buy limit for 24 hours
