Unprofessional and poor customer service

I received a call from their team this Monday 16th September 19 asking for my email, ID and told me there is a VAT to pay to have a package delivered to me. They didn't give me the cost. They said they will call me back with that detail. I asked them if they could get back to me as soon as possible and of course, they said yes because I have to pay within 72h.

On their website, I have found this two numbers: *** and ***, I am calling full days since 2 days, they do ring but nobody responds, if they have an agent or receptionist, they should fire that person because, since 9 AM to 4 PM no response imagine, I have called several times without success. This is very irritating. And I guess my email I sent wouldn't be attended and I was right. Probably after days since a simple call is an issue... or maybe months after
