should I file a case on interior designer

5 months ago

I came into verbal agreement with my interior designer on June 2023 for interior works of three bedrooms, fully furnishing 2 bedrooms and only ceiling lighting and paints for 3rd room, they promised they will complete in 45 days, they gave me quotation of 11,9200/- till now I paid 10Lakhs by end of september, only 60% of the work is complete, they are not lifting my calls, and the things they promissed and work on site are not matching, as of today november end,first their excuse was material got stuck in mumbai due to Ganesh visarjan, next the excuse wase labour is not available due to Dasara deepavali, now they are not responding at all, every thing is half done and shabby work, how should I proceed, I know their office and I have contacted with their assistant person, got to know these guys are habbitual offenders, he is suggesting to get the work done outside, head ache from last four months.

1)There is no written agreement, every thing was verbal
2)while giving money payments I took their signature in a note book.
3) I have their quotation and whats app chats
any suggestion would be helpful.
