HI there, we require a Calendars Months notice, so if you cancel Vuma before the end of this month, the cancellation wil be end of March, thus if you are planning to only move in end of April, you can cancel any time in March.
Once you have the Proof of address, you can place the order for the new Address via our website. I believe on step 4 of the application, you have the option to sign into your existing account.
If you require an installation, I recommend placing the order for the openserve package at least 2 weeks before you would like it to be activated.
If there is an installation already, typically it only takes a few days to activate the link, provided all the information is supplied(Such as Bnumber, and photos of installation) and no hiccups.
There is also a Relocation tab on your client portal, which you can also have a look at to assist in this matter.
Please let me know if you need any additional info?
