Inefficient service

Trying to contact a call centre agent to assist with a query... After listening to faulty music for almost half an hour, my call was answered by a rude lady. I stated my problem and she said I must call the accounts department. I called the accounts number she gave me and a recoding stated that the account is up to date and transferred me to a "chat bot" which was equally unhelpful. I am still no where with my query.
