[Resolved]  Infineon Technologies — they are harassing me by sending notices to mail with different mail ids each time and making calls to pay the amount

They are harassing me by sending mails from different mail id's and saying that this is the last intimation we are sending so pay the amount within specified time to close your file and recover from huge payment. I[censored] fail to pay the amount within the time then the company will file legal case against you. They are also saying that after filing the legal case the company will send the legal notice along with case id to your residence address. So if you won't accept, respond to the notice then the company will consider it as default and they can file legal proceedings against you and you will be in huge loss of money they mentioned. They are also mentioning some advocate name minhaz m patel. Please help me the way to recover from this issue.
