Universal Sompo — Not getting claim approved after all the verification done correctly

Sir,

i am very much disappointed from the service vo[censored]niversal insurance...
my car is in service centre since soo long and the agents o[censored]niversal sompo are making fake promises day by day...
my claim number is CL22291661
first the insurance company said that survey of my car will happen in 1-2 days that survey happened in one week.
then they said that 3rd party verification will happen in seven days that happened in 20 days
then after successfully verified on all parameters nothing was found wrong their 3rd party agent verified on all measures and said me that your car will be repaired in 2-3 days

now its been more than a month neither the approval of my claim happened and nor any response from the universal compant
