Continued Poor Service/No Communication

On Thursday, August 12, I posted a message stating my disappointment in service/communication from Discovery. On Friday, I received a phonecall, the caller said that she would be investigating and she would revert to me. On Monday, August 16, I received another call from the same Discovery staff member, apologizing for the error and assuring me that the problem had been resolved and that I would receive a refund in 3-5 working days. Nothing has been received as yet!! I suppose that is to be expected, it would have been different if I owed Discovery money. I have emailed the lady but have had no response.
