I joined https://m.solvelancer.com/ on 22 july which offers to solve the task.
Task include solving of questions of 8th, 10th, 12 grade. And promise to pay every friday. They take my pan card no. Aadhar no. Bank ac no and ifsc code. Stil not paying. After working 3 weeks. They refused to pay. My total amount is 1300 average. When i contact they rarely reply. I worked for 3 week i want my money that i earned in this lockdown situation. Hope you understand my problem. Kindly look into this matter.
