Looks more like 13 weeks than 8 weeks to me. Is this reasonable? Who do you complain to?
No, to me that is not reasonable. If the form says 6-8 weeks for the rebate, I expect it in 6-8 weeks. If they know their system takes 13 weeks then that's what the form should say. Anything less than that is false advertising. They should either revamp their system to meet the waiting period they advertised, or adjust the time period on the forms.
As for complaints, I would try to find some contact with the rebate fulfillment company (phone, fax, email, snail mail address) that bypassed first level support and actually went to someone with authority to cut the check, not just give you a BS excuse. That can sometimes be elusive, if not impossible.
If I received no satisfaction from the rebate fulfillment center I would then contact the store I bought the product from AND the manufacturer of the product. Again, regarding the store, I would direct my complaint as high up the corporate ladder as I could, nothing below regional manager. I would address the complaint to the manufacturer to the Customer Service Dept. I would explain the situation and stress to them that I bought the product solely on the basis of the rebate. I would also stress that I was a good customer, patronizing their store (or buying their products) frequently, and I expect them to honor the rebate they advertised if the fulfillment company would not. If this contact was in writing (letter, fax, email) I would address a copy to the rebate fulfillment people, to let them know you've taken it to the next level.
If I still received no satisfaction, I would file complaints with the Better business Burea (online form) and with my State Attorney General and include copies of that complaint to the rebate fulfillment center, the store, and the manufacturer. This usually gets their attention.
I had to use that last option once. I received a phone call the next day and the rebates in question within 5 days. This was after I had been given the run around for weeks.
As a side note - I am currently in a dispute with JoeExplorer.com regarding the $25 Amazon GC they promised for registering way back in October. The last person I spoke with from their company said it would arrive by snail mail before Feb 26. I just contacted them, reminding them that this was the third time they said there was a delay, and that the date they promised for receiving the GC was rapidly approaching. I informed them that if the GC did not arrive by that date I was going to file a complaint with not only the attorney general of my state, for false advertising and theft by deception (as my personal info, given at registration time, has value) but I was also going to send complaint letters to every company that advertised on their site, explaining their deceptive business practices and urging them to advertise elsewhere so as not to be associated with those kinds of practices.
We'll see if that GC comes.
