Address:

620006

Dear sir/madam,
I received order (21 august 2018).
Order id f2k22kfkgq
Pest repellent - ultrasonic machine.
This is poor quality and cheap product... It's does not work. This is useless product. And makes irritating noise which give headache.
Is there any ways to get refund? I have paid rs. 480/-
They are cheating customers
The customer service manager is not picking up the call nor responding the call. It is very annoying.
Please ask them to return my money
