Fnb home loan nightmare

Having been an FNB customer for so long, i must say i am disappointed in the lack of service i am receiving regarding resolving the double debit that happened on my home loan account. I have been calling, sending proofs and explaining the same story to different consultants every other day and at this point i am tired and done with this useless bank. I will be switching my home loan elsewhere and also switch to another bank because what i am receiving here is utter *******.
