I have shopped at v mart agra store for 7700 on 7th aug 2022. And returned back my home. After that when i cross check the items there is more quantity billed for 2 same bar codes. When i complaint at their store on same day they wer not accepting that and review their cameras after 1 hour they told me their executive will visit my house and verify the items. They are not replying on their own scanned bill
