How can I get assistance to claim a tax refund

Hello, I received a letter saying I was entitled to a tax refund. I tried to request it online, but when confirming my bank details constantly gives an error. On the letter, mentioned that if there were any difficulties, that I should ring the office services however I tried to call them this morning, as soon as they opened and they were already busy. Therefore, can someone please advise me if there is another channel of communication I can use, in order to have contact with them, so they can verify my details? Because I just need to be able to speak with one of them, to verify my bank details so I can have this sorted out. Thanks in advance
