Kaff Appliances India — chimney/hood and technician attending it

Address:

141 8th cross. 3rd main. RMV II stage (Dollars' colony) Bengaluru-560094, 560094

I have KAFF chimney in the tenants house which was never cleaned or serviced by tenants and pigeons were nesting in it for the last 2 years and they did not fix it. Now they have vacated and asked kaff technician to attend . He quoted Rs 6999.00 for parts and service. But my tenants asked him to meet them and it was fixed after a couple of days. And they it costs Rs 5500.00. But I had an acknowledgement from KAFF for only 850.00. I want to know why such large discrepancy in amounts, is there a shady deal going on between technician and tenant and are the parts fitted genuine as there was no warranty given to me. I called technician Mr Khalid, he never answers. Contacted KAFF team at Bengaluru/Karnataka state, nothing happened and they never called me back. Please, please HELP
