Lack of feedback from SAESI after paying required money for issue of Certificates

I paid a fee to have my daughter's FF1 and FF2 certificates printed, even paid the requested courier in October 2020. The institution made noise about my daughter's Leve 3 First Aid, they wanted to know who administered it and all. They got in touch with the said institution. To date, we have tried to follow up but nothing. We have tried calling, phones are not working. We have tried emails, we just get acknowledgement that their TAT is 72 hours. I don't know how many 72 hours should we wait for. Can someone tell me what the way forward is here, because no1 is saying anything.
