Vodafone India — network and data plan is not working

Hi, i have been a part of vodafone from last more than 3 year but this year throughout i faced connectivity problem and data network problem on daily basis. Sometimes i can see that its showing "e" in the world of 4g. From last three days, my network internet services is not at all working. I am using 4g network pack in my iphone x but its not working. Call drop is also going on frequent basis.
Kindly look into this.
And also i tried to port it but still not able to. I got below message as replied from their side:
"as per trai regulation, mnp services are not available till 15th dec'19. During this period, you will not be able to generate upc".

I really want to come out of this network because its very pathetic to continue.
