Disgusting service

I have been battling since 22 August 2019 to change my email address from *** to *** for both the Times subscription and for businesslive to which I subscribe. Despite numerous telephone calls and promises to sort it out the matter is still unresolved. I get the newsletter to both addresses then only to the old email address and then nothing. Currently I get the times to the old email address and none of the others. I have telephoned and get told they have expedited it. They give themselves 48 hours to sort it out and then don't. I have asked the Manager Lesley on two occasions to call me back and despite the operator saying he will he does not have the manners to do so. I was assured that Lesley would phone me back today and unsurprisingly he has not.
