Pre-ordered S9+ on 3/11/18, received and activated phone on 3/16/18. Started request for trade-in on 3/19/18. Verizon sent prepaid box, returned a Galaxy S7 to Verison received at their facility on 3/28/18. Received message from Verizon on 4/1/18 giving me a $97 trade-in credit instead of the $300 bill credit I was supposed to have received as part of the pre-order promotion. Three separate chat sessions with Verizon reps have assured me the correct credit will be given but has not happened so far. Has anyone else experience this problem, and how do I get through to Verizon and get the problem fixed?
It's standard operating procedure, as far as I can tell.
I had this same experience attempting to use the trade-in program on my S7 Edge when I bought the S8+.
Traded (four of) them in, and was notified that Verizon would be crediting my account for about half of what the trade-in program has promised.
Called probably six (maybe more) times over the course of about three weeks - each time waiting on hold for the requisite 30-60 minutes before speaking to someone - and each time I was told the situation would be resolved now.
Of course, it was not.
Finally, I went to a Verizon store and explained the situation to them. They claimed there was nothing they could do about it, and referred me back to calling Verizon corporate. After reminding them of just how many times I'd done that, they didn't change their position on the matter.
I then asked to cancel my (eighteen-year-old) contract with them, and inquired if they could direct me to the nearest AT&T store. At that point they offered to call on my behalf to see what had happened to my trade-in. That did finally resolve it.
Fast-forward to today - when I just got back from the same Verizon store. After calling Verizon corporate three times during the last three weeks (again, waiting 45 minutes or so each time) to ask where my shipping boxes were so that I could return my four S8+ phones - I still did not receive them. What I did get in the mail yesterday was a single shipping label for one phone, and a note on how to return my "defective" merchandise.
The local Verizon store this time claimed they could accept the phones and return them for me - and so I did.
It remains to be seen just how many additional calls it will take to actually get the $350/24-months applied to my four lines.
This is all, of course, by design. If even a fraction of their customers give up on the process due to frustration - it is just free money for VZW.
Best of luck to you, and just know that if you do persevere that you will likely get the trade-in value. Just be prepared to spend literally hours on the phone to do so.
