Vodafone REPEAT TO WIN Offer

Vodafone is running this offer of repeat to win...
Well , i am not interested in the offer, but does vodafone stack the recharges like how Jio & Airtel line up back to back recharges, so once the pack is over, automatically the next one is activated, or they still start all packs which they used to do earlier? Have they learnt lessons from Jio & Airtel or they are still reading old books?

I don't think they can read yet.

Thanks ... So they would start all recharges together...
They really have no brains and launch stupid offers to fool users.

Asked Vodafone in twitter.

Update:
Vodafone does merge the recharges and extends the validity.
I recharged 449 recharge which currently gives 4gb per day for 56 days for three times. So they gave validity of 168 days with 4gb/day. I am not sure if you mismatch different recharges what would happen...

works on airtel.. does not work on vodafone karnataka.
