What angle did you play to get that? I'm with Fido too, haven't been with them a year yet, and I'm on the regular ol' $65/month iPhone plan. I was on a plan similar to your original one up until a month or two ago. The more I read, the more I feel like I'm getting screwed paying that much for what I get.
And I won't stand for it any longer. Now all I need is a tried and true reason, other than that I'm getting a comparatively lacklustre deal when compared to a group of people I don't know.
After cruising RedFlagDeals and reading about all the deals people got I figured I might as well try.
I called into Fido and had to deal with their customer service lackey at first, told him I wasn't happy with my plan. I had to explain to him several times that people out there were getting better deals than me with similar features.
He then transferred me to Customer Relations (not Retentions strangely enough.. guessing they're the same though) and Anna was really snappy with me.
She assumed I wanted to leave but I told her Rogers and Bell customers were getting better deals with similar packages.
She got a bit agitated and started telling me to forget about other people and asked me what I wanted. I told her other people were getting:
200 minutes + 6gb data + iphone value pack + 2500 sms etc; for $45
And she said I only use 46 mins on average and then I told her I wasn't exactly looking to up my minutes.. I just wanted a better price. I told her my intent wasn't to leave but if there are better deals out there that I would be inclined to leave. She then told me my cancellation price would be $400 and put me on hold.
She came back and offered me the deal I posted above. Initially it was that minus Visual Voicemail, just regular voicemail instead which clocked in at $57.50 plus a $5 credit for 2 years. I said I needed Visual Voice and she said I would have to pay $5 for the 2500 SMS and then she could add in Visual Voice because of the way the promo was setup and I said fine.
So we agreed to $62.50 with a $5 credit which comes to $57.50 plus HST.
woah...how did you manage to get that deal

my current plan is similar to your old one
I'm paying $75 with taxes
150 anytime minutes
after 7PM unilmited evenings/weekends
no visual voice mail, who called, call/name display
6GB Data and 125 text messaging I think
I've been with them for 4 years now... maybe I should give them a call
hopefully I can get something like yours
You might have a better deal than me because I've only been with them 1 year.
Call Fido and ask for the retentions department and say you got an offer from a competetor and see what they can do to keep you. Negotiate from there.
It's not as easy as that, you have to deal with the customer service guy first before you can get to retentions.
Make sure you go in with guns loaded or else they will rip you apart.. as I found out the first time

Also, be nice and polite to the retentions / customer service. Getting mad won't do much. Still, be firm and tell them you're looking for a better deal because other customers are getting better prices. These guys are just normal people doing their jobs that have to deal with the next fussy customer so try and make it smooth for them and they will make it smooth for you.
