Just walked into a Sprint store and the manager tells me that he can no longer renew my contract with my Sero premium plan as it doesn't exist in his system. The other rep first tells me that you can still do it over the phone or you can change you plan in the store, renew your contract and change it back to the Sero premium afterwards on the phone. I am a little bit wary about trying his second method. Anybody recently renewed their contract with the Sero premium plan?
