Rogers retentions isn't what it used to be unfortunately. I just talked to them a couple of days ago and they offered me the same as what they offered you, but after going back and forth they finally said they'd give me the 3GB option for $65, including canada-wide minutes. I didn't take it as it's quite a bit more than my current plan with them (sig below), but they left the notes on my account with transaction ID in case I change my mind. Funny thing, they looked at my current plan and they can't even match it right now, said I had too many credits (4 in total), and now they only allow 2 credits max (one for voice and one for data), but I'm not sure if that's just a line I was fed or whether it's true.
I was really hoping for some kind of family share plan but all they offered were outrageous $120+/month plans. I'm going to look at our corp plans with Bell next week and see if they can do something so I can finally add my wife on my line and get her an iphone 5.
