Buzzmeeh — mobile screen changing

Its very bad that i am writing this type of worst review. I paid 2100 for screen replacement on 23th february 2019 but after that touch is not working smoothly and back camera has blurred. I have told to mr. Antim ([protected]) for these problems, he is a customer care executive at buzee mee. But he is giving me excuses only. He said ma'am our employee will come and check the issues but till date no one has come. Even i mailed 2-3 times and also contacted on whatsap and calls but they are not giving me any positive response.
