I am not sure of the retention plans in Chennai. But being a Vodafone Postpaid user in Kolkata I can say that there are retention plans in Kolkata. I myself got the Lifetime Postpaid plan (Zero rental plan with only Rs.49 towards CLIP charges) way back in 2008 when I threatened to migrate my no to prepaid. Any yes...Vodafone Kolkata offers Unlimited Blackberry services at Rs.399 in postpaid provided you place a port out request...!! (Some of my friends got UL BB at 399 after raising a port out request).
I made 2 port in from Reliance CDMA to Vodafone in Jan-2011, one Postpaid & another Prepaid. I must appreciate that Vodafone has given me very good plan in postpaid but now when i wanted to transfer that PREPAID into Postpaid as my add-on card, Vodafone Retention Dept. was so harsh they don't bother to retain their loyal customer. I explained my genuine offer which i got from LOOP mobile if i convert my both SIM to LOOP I can get 800 minutes+1 GB GPRS @ Rs.99 + 300 SMS + INTERNAL CALLING free between two mobiles at Rs. 199/- each rental. Whereas i just ask VF to provide me same plan to my addon which i am availing on primary card with Internal calling free. If they simply denied my humble request I would have no objection for that but to my surprise they advised me to get that LOOP offer, so now i decided to switch over to LOOP just to avoid such arrogant attitude of vodafone.
@Vodafoneindia, As i mentioned in my post, your C.C.people are not so polite to listen my humble request which i already made earlier, i am having 5 other mobiles in my family & Loop is providing me attractive offer as porting scheme (800 minutes+1 GB GPRS @ Rs.99 + 300 SMS + INTERNAL CALLING free between two mobiles at Rs. 199/-) so now if you can provide me any of your executive numbers i can communicate with them anticipating to retain their loyal customer, as i am not allowed to send you PM so i am unable to share my principal number,waiting for your prompt action.
