Lenovo — Provided defective product (Tab M10).

I purchased a Lenovo Tab M10 from Croma - Connaught Place on[protected] for 15990 INR. The product worked for a short duration only (with issues in charging) and finally got switched off due to complete failure of charging. Since the product had one year warranty provided by the Lenovo company itself, i returned the Tab to Lenovo (through their service centre in Srinagar - J&K, on[protected] for fixing the problem. I have been now waiting for my tab since, because it has not been delivered to me so far despite my repetitive communications with the concerned authorities from the said company. Now i want that either a fresh tab be delivered to me or my money be refunded, for it seems like they are not able to repair that defective Tab. I request this forum to kindly take the cognizance of the matter.
