Yes, this is one of MANY phone numbers WaMu uses (they call from WA, AZ, GA, NV & the list goes on). The part that is odd is that they don't respond when I have had the ability to answer any their calls. All because they will not consider payment arrangements we have attempted to make with them. I am going to just start turning my ringer off.
This is WAMU or a company that is working with WAMU to collect on credit card debt. I don't suggest you talk to these schmucks on the phone. Call Washington Mutual directly about your account.
They call me multiple times a day and in the evening after 8pm. I'm not dealing with them anymore. I asked them if they could help me by halting or elimating or even just lowering my APR so that I had a fighting chance on paying them. They refused multiple times and after many attempts... I'm just going to consolidate it instead. 29% APR is just ridiculous.
