Disappointed with customer service

I haven't been getting good customer service with mondo I try to call but nothing works I wrote a private message here on hello Peter but I haven't received help. I ordered an iPhone to which I was told it will be delivered in 3 days it's been a full week I haven't received it yet I've accepted their debit order on my app I was sent a link to which I had to verify myself but it ended up not working I have tried to contact them for a new link I still haven't gotten help they haven't called back nothing.
