(Message from customer service
hello,

i understand your concern regarding the vodafone recharge of your order
#[protected].

i've reviewed your email and understand that you've recharge the pack by
using freecharge.

as per your concern i've checked the status of the offer and see that to
avail the offer you should have recharge the amount from amazon.in.

please check the below steps to avail the offer:

1. Buy a smartphone from 4th october, 2017 to 8th october, 2017 on amazon.in.

2. Once the new handset is purchased, recharge your mobile with a 1gb or
above data pack for the prepaid sim to be used in the new handset.

3. The purchase of the smartphone and 1 gb or above recharge should be done
from amazon.in to be eligible for the offer (Eligible recharges mentioned
below). The recharge must be done only on amazon on or before 21st october

4. Post recharge you will receive an optin notification via sms within 7
days. This sms will have a link to opt-in.

5. Post this notification, you need to opt-in the offer at my vodafone app
using the link received by sms.

6. Once the offer is opted in by customer, an additional benefit of 10gb
will be credited within 24 hrs.

7. For subsequent 5 months, the 10 gb benefit would be credited along with
every recharge for 1gb or above data pack.)

When i recharged first 148 i did not get 10gb so i called them then after so much of convincing and talking they gave me my 10gb.

But when i recharged this time i did not get 10gb data and when i call them they keep giving ridiculous excuses that don't even make sense. All customer care executives just want to avoid the problem falling on them.

I talked to customer care representative named swati (Name may be fake given by her)
Her team leader also gave same excuses jasmine (Name may be fake).
