Sathya Agencies - Charging more than market price and neglecting customer complaint

I have bought a Acer swift s* laptop from Sathya on April *th, They told its ***** cost. Since i had one of my friend working there, i did not cross check in the internet i trusted and bought it. I made a downpayment of ***** and rest i paid through bank debit card loan. After coming home i verified online it was only *****. Also the signin option in laptop using fingerprint is not working. When i inquired the center, they said its a mistake on their side and asked me to come two to three times to shop and they said they will give me any other item for the rest of the money and provide servicing for the laptop. No servicing was given. I accepted and requested for a Freezer and Vacuum cleaner for the remianing amount. Then they told the amount is not enough for these items, again they said they will refund the whole amount and one person came to my home and took the laptop and accessories. I accepted and this happened till **th of April. On **th they said i will get refund by * week and the loan will be cancelled. Now on **th if i ask the manager is neglectly telling me that i never knew they took laptop back, we never processed anything, it will take another * days to process refund of your down payment and then i need to pay * months emi even though i have cancelled it only then refund will come.
Being a single woman handling this I am totally frustrated with this behaviour. I was made to come to the showroom unnecessaryily for * to * times, yet my problem is not solved and i have to pay emi now without having the equipment, and on top of that i am not sure what other stories i have to listen after paying * months emi. I totally dont recommend buying any products in Sathya. Double check the market price, they are charging a lot more than other places.
