Mi az a paysafecard és segítene valaki értelmezni ezt a munkáltató által küldött levelet (angol)?

Tesóm kint van Angliában 2 hónapja. Jelentkezett mindenféle munkára és az egyik helyről ezt írták neki vissza:

"... It is very important to email us back with your uniform sizes comprising of shirts, trousers, safety boot size and also most importantly your paysafecard £50 payment voucher numbers for an enhanced CRB [criminal record] check to be carried out through our crb specialist agent to ensure an accurate criminal record report.The company will strictly only accept crb done through us for security reasons due to the nature of business of the company you will be working in,no other crb report will be accepted and you will not be employed if we do not receive your email with your uniform sizes and paysafecard £50 voucher numbers for your crb fee before the deadline date.

The paysafecard voucher is a new safe and secure payment method that we use for effective payment for crb fee. The newsagent shops, off licence shops and mobile top up shops with the paypoint services can issue you a paysafecard £50 voucher,once you give the shop assistant £50 in cash.The paysafecard voucher numbers is what we require you to email back to us for your crb payment fee and also to ensure that your job placement is still effective.The crb fee will be refunded on your next salary.The company will cancel your induction and training if you do not email your uniform sizes and paysafecard £50 voucher number for your crb fee before the deadline date.

The deadline to email back to us your uniform sizes and £50 paysafecard voucher numbers for your crb fee will be on Tuesday, 4th of March 2014,no work placement will be offered without any of the above and you will not be eligible to come in for the induction and training .The company will not accept any late email submission of the above due to the high volume of successful applicants. We are extremely very busy this period with the recruitment process and may not be able to respond to some of your enquiries at the moment,you will be given all the information needed on the induction and training day. We look forward to welcoming you to our company."

Azt mondja, hogy nem igazán érti hogy miről van szó, pedig az angolja egész jó (alapból telefonon érdeklődött először, tehát megérti amit mondanak neki). Én előtte egy évig voltam kint, de én pincérnő voltam, nekem nem kellett ilyen.

Valaki tapasztaltabb tudna a segítségünkre lenni?
