Glitch on online portal

Please note it is impossible to reset a user password on your website. Your system generates an OTP and a temporary password, however it refuses to accept any new passwords with a standard error message of the special character used in the password is too common. No matter how many different variations of the password is supp****, the error message remains. I tried to call your customer care line, but the person that assisted me did not understand that your system literally blocks your clients from generating new passwords.
