Their Bitcoin transaction is not instant both buying and selling in fact it often take days before it can be implemented.
Actually, with our new services, you can now instantly exchange Bitcoin to fiat and fiat to Bitcoin. Payza now lets you hold Bitcoin in your account and convert Bitcoin into most fiat currencies supported by Payza. Your transactions will still be subject to review when you withdraw these funds from Payza (so when you send fiat or Bitcoin to a bank account or external Bitcoin wallet), but if you would like to make instant exchanges, Payza now offers that service.
We are also working on a feature that will allow instant Bitcoin to Payza Card loads. So we will soon be offering a service that allows you to instantly sell Bitcoin and load your Payza card with the USD funds from the sale. Those funds can then be used anywhere the Payza card is accepted: online, in-stores and at most ATMs. Stay tuned for more updates.

I am happy to see a committed and dedicated support of payza here, i equally appreciate your response but you only cover one aspect of my question which relates to delay in exchange.
Can you say something about your high transaction fees ?
