i don’t want upgraded graphic card laptop, it’s low price laptop and bad user reviews are there for this upgraded laptop thats why i went for intel 4400 specifically and also wifi card mismatch is also there.

For more information to informing you that for following model laptop :
Evalue Code : Z555103UIN9 : Intel HD4400 (Graphic card) —> WLAN (wifi ) card is 802.11ac (Intel 3160AC + BT4.0 802.11ac + Bluetooth 4.0, Dual Band 2.4&5 GHz, 1×1) where it more upgraded and cost more .
Evalue Code : Z565105UIN9: Intel HD5500 (Graphic card) -→ WLAN (wifi ) card is 802.11n Dell Wireless-N 1705 @ 2.4GHz where it lesser cost .

First i asked the paytm for compensation for price variation , Now paytm is saying you got upgraded laptop we won’t compensate but i don’t want intel HD5500 one laptop asked them to take back but they are not responding .

Paytm f**king indirectly . Wasting time and mobile bill to call them .
And first thing paytm customer care bakwaas , they don’t give proper resolution .
Shame such a big e-commerce website is maintaining poor customer support .
