Vてもらう in Kansai-ben is the same as standard Japanese, but the past tense from the dictionary form^? is different. The standard Japanese Vてもらった becomes Vてもろた or Vてもうた in Kansai-ben. もろた is the base for in Kansai-ben, but may become もうた in use.

Please be aware that there is another, completely separate, Vてもうた that expresses repentance and regret.
