I moved house not so long ago and although I had some issues to do with clerical errors which took a while to sort out, the actual process of doing the move online was pretty straightforward.
Can you describe the error message you are getting?
I know nothing about Whatsapp (or what it even is, for that matter) but the phone number is working. Right now, there is an overwhelming demand on customer services thanks to the recent energy crisis, tariff changes, EPG and all the rest of the craziness, but they are doing their very best to deal with unprecedented numbers of customers enquiries.
My advice, based on what a lot of people say on here is to start dialling the Customer Services number at 9am on the nose, if at all possible. There will still be some waiting on hold, but it is a Freefone number and you should be able to get through before the queues really begin to back up.
