Please retweet this!  Fido billed me $19,763 for data that I was alleged to have used while I was in the UK.  Only problem is that the time period in question I was breathing out of a machine in the hospital.  I am fighting with them at the moment. They agreed "graciously" to drop it to $1500 and despite assurances that no amount would be taken out until the matter was resolved, they took $4000 out of my bank account.  They won't give me details of why I was billed or who billed them (claim it was international roaming).  They even refused to disclose the name of the carrier.  They claim I used over 500 MB of data which was impossible because 1) my data roaming and 3G was off (I always check this before I leave the airport at home)  2) I was hooked up to a machine to breathe during the alleged period so didn't use any wifi in error or anything else that could explain it 3) iPhone did not leave my room 4) my company uses all Apple products and iPhones and I am VERY well versed in how to not get billed for roaming given that I travel a lot (2-3 times a month).  This is ridiculous.  When I asked to speak with a supervisor yesterday, they refused and said someone would call me back in 48 hours.  I insisted on speaking with someone and they said no. My company has 4 iPhones with Fido we spend close to $4000-$5000 a year with them. I've been a loyal customer since 1999, despite many, many huge blunders Fido has made over the years.  This is my breaking point.  No one at Fido seems to care about my time or my business. Any advice?
