Trai — sim service expiry

I am very disappointed to be told that my phone number will be discontinued on account of service expiry. When i go to the nearest vodafone store with my valid documents (My new zealand passport and 5-year india tourist visa) they tell me they are not interested as i'm now in pushkar rajasthan and the sim was purchased in delhi. This is not good enough for an international company like vodafone. It's time india was able to service customers india-wide and not state by state. Each time this happens i loose money and time. It is so frustrating! I want india to be great, but each time i'm here i wonder if that is ever going to be possible.
