Whilst we are happy to talk to people on the phone, where there are a number of issues to relay you may find it easier to put these in writing setting out the points clearly.
Er y byddwn yn falch o siarad â phobl ar y ffôn, os bydd angen i ni gyfleu nifer o faterion i chi, mae’n bosibl y bydd yn haws eu hegluro’n ysgrifenedig.
