Horrific service and no client dealing skills

Times like these that I wish there are less stars! I have been waiting 8 weeks for a benefit to pay, just to follow up with the claims consultant telling me "oh, I do not know how I missed this claim", this was in the 7th week on the Wednesday, she promised this will be dealt with immediately, just to realize that a week later I called in and spoke to a manager, that it was not dealt with immediately, it was only sent through 2 days later for something else, with the consultant telling me that I did not hear her clearly, she told me this, and today after I followed up again, only for tax. It makes me think, that my claim could have been sorted out within 2 weeks a most. This is horrific service.
