Just beware here, Paycent is no longer issuing a mastercard. The card has been changed to a unionpay card. Unfortunately you will only find out, when you receive your card. Paycent does not deem it necessary to inform its customers about "minor" changes like this.
Card was originally announced for the end of February. Now the date for delivery of second batch of 4th or 5th of July. Again Paycent doesn't really deem it necessary to inform customers of delays. The only place to get any information is their telegram channel. But that is quite a challenge to retrieve the few gems of valuable information amongst all the fanboyism talk of the investors.
If you don't want a unionpay card (because you paid for a mastercard after all) you can try to get a refund. Good luck with that though.
You will soon realise that they keep no records when customers paid. The will ask you to send them the transaction hash of when you paid the US$140. Okay that can be a bit of an issue if you use multiple wallets and have many transactions. However if you ordered and pre-registered through the website (and not the app) now is when your real problems will start.
Because of a bug on the website the price in BTC was not updated once you pre-registered. So if you didn't pay on the same day that you registered you will have payed more (or less if you are lucky) because of the fluctuations in the BTC/US exchange rates. If you belong to that group and only payed a couple of days after pre-registration, your amount from the transaction will likely differ. Once you send them the transaction hash they will tell you it is not the correct hash because well the amount you paid is more or less than US$ 140.
"And please send us the correct transaction hash."
If you want to check for yourselves and not just take my word for it their wallet address is 33mUPvJK29cCB7Uo6xy11L5dcczjBdSbbG

Now scroll down and check how many payments they received that were spot on $140 and how many were more (some as high as US$ 155) others less.
In my case I pre-registered in January and it was only when I asked for a refund that I became aware that there had been a problem with the initial payment. Paycent never bothered to inform the customers. Even though they are very much aware of it and are now utilising it as a cheap trick not to repay the deposits.
There are other issues as well, bugs in the app, payments that get stuck and need to be be retrieved manually, a process that on average takes three days to a week.
So at this stage my only advise is steer clear of paycent until they get their act together.
