I’m not sure that there is any documentation on this; however, you should be able to still walk into a store and receive a replacement. To be safe, I would suggest calling customer service first and ask them to send you a replacement, or arrange for one to be picked up in store.This is a legacy plan, in which only telesales can help you, not even corporate stores can even process an upgrade....
So the question is, how do SERO customers deal with this exchange?
