Highway Robbery

I was charged $45 for a balance of $425 I had deposited. I was only able to send $$380 as a result. This was the last transaction from me. In the 3 transactions I sent today, you vhsrged $63. This is outrageous !!!!!

I Wii NOT be recommending your company to anyone!!!!!

Not what I expected….

When the initial quote is listed, and you choose this vendor, the service fees are not yet included. Therefore, your actual cost is considerably higher once you go through the process of providing all of the details for the transaction. Fees are considerably high, compared to others offering the same service.

Respect for the customer!

I particularly appreciate the security and validity checks of emails before final validation, as well as the email updates at each stage, which allow us to know where we stand.

So far, there's no need to contact support; everything is well explained and tracked at each step.

The processing speed is excellent.
