My Complaint is still unresolved even today

What a shocking service from fnb, I had complained recently about the issue of changing from Cheque to Savings account, I have been contacted and was promised that the account will be changed. This request was made on the 15th December 2017 but no one bothered to action the request. I disclosed to the consultant from the customer relations department (person who responded to my hellopeter complaint) that what will happen to service fees/charges that I have been accumulating since my request in December, the consultant advised that they will look into it, see if I could be refunded based on the savings charges. Yesterday, I receive the bank statement and I am still accumulating cheque account charges. Please contact me asap
