Berger Paints — poor quality of work by express painting and non attendance of complaint

I am Abhishek I given complaint on Xpress Painting to customer care with SR[protected] dated 18 Oct 2019.
The complaint was for carck on walls and paint peeling off.
Till date the complaint has not been attended. It has been 5 months now.
Following persons were named by customer care as executive for attending the complaint.
Mr. Sunny Kumar Thakur
Mr. Piyush
Both the persons have always made fool by just saying "It will be done in a day or two".
This is simply a breach of trust between the customer and company as after having paid the amount the company has simply ditched the customer.
