Vodafone India — port out for mobile number [protected]

Website:

www.vodafone.in

I had applied three times for port out at vodafone, but vodafone is not processing my request. Every time I contact to vodafone customer care they are saying it is in process and will be done, but till date port out process is not completed. They have now blocked my number from contacting to their customer care.
I had applied on 6 march 2018, 22 march 2018 and 7 april 2018.
