Welcome to Vodafone Community
I was a Vodafone customer for many years as was most of my family but after being offered an iPad for a great monthly price as an additional line and being sent out a regular tablet I contacted Vodafone, after calling to complain and cancel the tablet and waiting for the call to be listened to I eventually heard back saying they apologised and this should not have happened etc, which I accepted but I wanted to tablet line cancelled. Shortly after this my phone was also disconnected and I received a letter demanding over £300 to settle my phone contract which should not have been cancelled, I have sent numerous letters that were signed for by Vodafone staff and received no reply and they have issued a default account on my credit file for this and still had no reply to around 10 letters.
Please let the Social Media Team here who read all posts catch up with your post and I'm.sure they'll help you with this situation if they can.
