All providers are good untill something happens, i was with vodafone for ages swore by them until they had a Internal re-shuffel in the firm and as with you they stopped booking the payment from my account,after getting in touch they said oh yes we have changed our software and that was the reason thank you for letting us know.
one week later like you got a letter saying that i had not payed my account dues, and were being cut off........................................ end of story.
I cancelled my account with them with so much hassel that i nearly went down to head office to knock off a few heads.
Finally changed to T-online,although i have not had any problems as to yet i believe it will be a question of time before some thing happens......
You can please some of the people some of the time, but never all of the people all of the time........
Here i lay my case your Holyness
