No response to email

Sometimes one doesn't really wanna go via this platform to get help from the institution, but because of not taking customers serious one find themselves having to go via Hellopeter to get help, i have sent the institution emails requesting a refund to no response on the 30 October 2024, i sent an email to *** and *** requesting my refund they never responded to my email, it's more than 72 hours now, i decided to give it time then on the 05 November 2024 i sent an email to ***, *** and *** and again on the 06 November 2024 i sent email to ***, ***, *** and *** still no response.
