Sharp India — I am complaining about my sharp inverter a.c

I am complaining about my sharp inverter a.c regarding its service and low cooling for the last two weeks. I called the customer care no. umpteenth times but to no avail. I called Mr. Jaspal Singh who is the branch manager and whose contact no. is [protected] many a times but he also gave me false assurances everytime. And as if it was not enough, to rub salt to my wounds, he blocked my number as if I had committed some wrongdoing. My complaint no. is 19201. please for god sake sort out the problem at the earliest or I wiil have to approach the consumer forum for the redressal.
