I was a Talk Mobile customer and I was told that I was eligible for upgrade due to Vodafone buying them. The customer service assistant told me I would be on a £18 a mobile a 50 % discount for joining from Talk Mobile. A week or two later, a letter said it £36. I was assured by two different assistants that it would be reflected on my next bill. When I was finally put through they said they don't know anything about that due to the assistant "forgetting" to put that in. have been on the phone for over 30 minutes to sort this issue. I haven't been with Vodafone for 9 years but took a chance on them and now I regret it.
