A: I haven't received my credit card bill yet. B: Which credit card are you speaking of? A: My Master Card. B: We sent that bill out a couple of weeks ago. A: I never got it. B: Your bill was mailed already. A: What am I going to do since I haven't received the bill? B: If you haven't gotten it yet, then you should probably take that up with your post office. A: Can I get an extension on my bill if it does happen to be the post office's fault? B: If that's the case, you will need to provide proof of their mistake. A: Thanks for everything. B: Don't mention it. Call back if you have any more problems.
