No service in England.

My third time I'm writing now. I changed my contract, and it was supposed to start in August. I'm located in England. After the changeover I don't have a service. When leaving South Africa I started sms roaming and it worked well under the contact in England. Now I'm doing my own fault-finding after the changeover as I feel very little support from Vodacom. Their customercare email is totally useless. I believe if they activate sms roaming on their site and the problem may be resolved unless there is something deeper that I'm not aware of. What you will never get from Vodacom is to get to a stage to ask you ''Anything else I can help you with?''. I've been their customer for 20 years and could have been for many more, but looks like that relationship is going to come to an end soon. It's just not possible for me to be physically available to sit in their offices until the problem is solved. Sms roaming or whatever it is, in the end of the day I don't have a service. Maybe Vodacom doesn't operate in England anymore? Maybe they stopped their services to England at the exact same time I changed my contract? Let me know is it better to cancel my contract?
