Contacting ETASA/Transporte Terrestre

Does anyone know whether ETASA/Transporte Terrestre has communication by WhatsApp?

It’s website says,

I sent email weeks ago asking to reserve a taxi to Troncones for my 8:00 p.m. arrival on October 12. I haven’t received a reply. I wonder if the email address is not monitored or whether it is not a correct/current email address.

I could try telephoning them, but given my limited Spanish competencies, I don’t want to risk messing this up.

They may be a little slow on their e-mail. Give'em a call!
