Well folks, it was a chargeback.
The client, for whom we are still doing work, has advised he has not initiated this but when spoke to the bank, they said the card had been reported as stolen.
Anyway, we sent all the proof of works complete to paypal together with emails between the client and myself confirming the work was done, payment made an authorised.
However, paypal still decide togo ahead with the chargeback. So I will NEVER use paypal again. Its hard enough anyway being self employed but it doesnt help when we receive no protection of customer service from our payment services.
As for paypal, all the horror stories we hear are true and for that reason, we will not use them again.
