Changed my price plan early July 2015. there the trouble begun. first I didn't have any service at all abroad for 2 weeks. That then got fixed somehow. However, using mobile data didn't work... for nearly 4 months!!! I sepnt hours and hours, countless e-mails back and forth, with Vodafone customer service giving me the ever same useless answers. Nothing worked. Talked to someone new almost each time. Web chat is just as useless and so are their reactions when you twitter. As said it took almost 4 months. Now they disconnected and reconnected my phone. with the result that the services work, but I have to start over with installing spotify, I cannot access my account. they keep sending me SIM cards to wrong addresses.... seriously, dealing with Vodafone has been a nightmare. The worst customer services by far I have ever experiences everywhere. It is actually hard to believe that you get such a concentration of incapability, incompetence and indifference combined in one place.
