Vodafone — Missed call services not working in Roaming

I have vodafone number since very long time.

I was in Mumbai and number belongs to Mumbai Circle.

Since I am using this number for Business purpose i am very serious on the output.

Already Vodafone has lot of network problems in Pune and other rural cities.

I am chasing them in writing since a year for MCA services but the are saying MCA services are not available in roaming.. Horrible how come this will work. what is the use of this paid services then. I am in Pune now in Maharashtra circle and having lot of VI network issues and loosing many important call. Still i adjusted that, but requested them to atleast send me message so I can call back to my caller.

But no response from them..

Important point is that, I have another number in Airtel with same mumbai circle and they are sending messages for missed calls. How?

Now next i will approach to TRAI for this..

Another chitting approach, or their software fault, they were charging me twiCe in every month for more than 1 year may be. It's stopped when I noticed them.
Said will refund extra paid.. but no track of account or no summary email communicated to me.
