Lost passport with TLS Contact for over a year

We app**** for my husband's UK Visa with TLS Contact late in 2021 but in plenty of time, the application went through and it was being delivered by DHL but then lockdown came and the delivery was cancelled. We were so disappointed that I had to go alone to the UK that when I got back I didn't contact DHL for a while for his passport. When I did they told me they returned it to TLS. So after much searching for a way to contact TLS Contact, after only getting an English phone number that I can't call from South Africa, I fill out a feedback form to ask where my husband's passport is and only get automated responses. I don't know how I can actually speak to someone and explain the situation to find out how we can retrieve the passport, with or without a visa, we just have been without his passport for over a year now. My latest communication with TLS was as follows:

01/10 - filled out another form on their website as no other form of communication available 01/10 - received automated response 04/10 - forwarded to local team 26/10 - contact centre has provided response and associated inquiry is closed

Does anyone know how to contact a person with them?
