Isango! / Avoid them
I would recommend you avoiding booking through this rip-off company.
Can't say anything positive. When I had troubles they promised me a lot. Each time I called them to find out how it was going they never were helpful. They have been giving me a runaround for 3 weeks with no results.
What they need from customers is money only and it's sad. No one wants to provide a normal service. I am very disappointed I dealt with them.
