Transitioning between Cambridge Early Years and Primary - with Dr Alison Borthwick

[@jamesladeji4344]

Hi. Please, I need help to book for the online Cambridge IGCSE Teacher course for English as first language in Nigeria. I have started the process but encountered a problem at the payment stage.. I have sent several messages to Cambridge by filling an online form but got no response till now. The main issue is that the portal is not recognising the nvoicing centre number I input but kept asking for a valid one. I have confirmed from the center that the number I input is valid. Yet the portal did not recognise it as such. What can I do next? Thanks.
