My bulb account says a different address

Hi my switch to bulb is happening tomorrow 15/12/19 and when I go onto my bulb account it says a different address on the top of it when I called bulb on Wednesday or Thursday just gone and told them they said don’t worry we will change that checked a few things and said it is definitely the right meter we are taking over but I’m still worried that the address on my account is wrong and don’t know wot to do as it’s not possible to call them till Monday now and the switch is tomorrow plus I’ve had to top it up £40 as mines a smart meter and it’s a card not key so had to go monthly by direct debit the first 1 coming out this time in January so I’m a little confused and worried any suggestions are welcome thanx
