Gleam Technologies — I am complaining about payment and customer service

Dear Sir/Madam,
I mailed and called you many times but did not get any help from your company’s executive. All said that they would help me and would give reply of my mail. So I have been waiting for many days. At last I took decision to complain on your site. I think now you can help me.
I took project from your company on Thursday, 29th August. Then I got 1500 rupees. After that I informed it to one of your executives named Preethi Raghav. I took project under Preethi Raghav. But after getting registration fees and asking some questions she blocked me on WhatsApp. Then I messaged from another phone number. Same thing happened. I called on her number but saying does not exist. Then one of your executives said to send agreement copy and qc report. I sent but no reply came. Then after many days a reply came from email for sending bank account details. I sent. Then again same thing happened. I did not get any reply till now. After that an executive named Priya told me that she would reply. But again she did not give reply. One executive told that she informed all things to Preethi Raghav. Yesterday I called but no one could help me. I have screenshot of calling and chatting on WhatsApp. I have attached all things below. Please check.
I want to work with your company. I need payment. If you cannot maintain all the clients properly, how will I work with you? Then anyone can think your company is fraud. Your company has email for supporting. But you do not reply of email. Then why have you kept this email? Just for showing? If you do not give payment, say directly. Then I will not waste your time and also mine.
I request you to look into the matter as early as possible and give payment and give me a responsible executive to work again with your company.

Thanks and Regards
Mahadeb Mondal
