Address:

Mumbai City, Maharashtra, 400024

Today I went to Reliance store chembur to Chembur. It was most pathatice experience ever in my life. The staff was least bother to attend the customer. After waiting for half hour the lady ask me about me about my number and told me to pay 230 as my monthly bill and 150 as MNP fee for which she was not ready to give any receipt. This money which they take is completely in cash and without any receipt with no records. It is encouraging black money . Kindly confirm if reliance mobile or any other broadband instructed the dealee to take MNP charges in cash and not giving receipt. 100 people per day 100×150= 15000
100×150×30= 4, 50, 000 Rs w/o any receipt.
