Wrong company name on start up page

I'll provide different information about deleting your QuickBooks company , mekahelpdesk-gma.

If one of your QuickBooks Online company is less than 60 days, I'd suggest purging your account. This way, the system deletes all possible data entered into the company, and you're unable to restore or reverse them. Please keep in mind that this process only works for QuickBooks Online Plus, Essentials, and Advanced. Here's how to purge: 

1. Log in to your QuickBooks Online account.
2. Change the URL to include /purgecompany.
3. Example: URL shows https://...qbo.intuit.com/app/homepage, change to: https://...qbo.intuit.com/app/purgecompany.
4. The next screen will provide a summary of the items to be deleted.
5. Type the word “YES” once the data gets deleted, then click OK.
6. Click Wipe Data once your selections are complete.
7. Once the deletion is complete, you will be rerouted to your home page.

However, if your account is 60 days old or older, you'll need to cancel your account to delete your company. This way, you can start a new subscription to create a new company. To cancel your account:

1. Click Gear icon at the upper right corner. Then,  select Account and Settings under Your Company.
2. Select the Billing and subscription tab.
3. From the QuickBooks section, select Cancel.
4. Follow the steps to cancel your account. If you use payroll, you should cancel your payroll account too.

Once you cancel a QuickBooks account, we hang on to your data for up to a year. Thus, your account will stay under the Cancelled Companies section when you login. This is to make sure you can still have an access to your account in case you'd like to reactivate it.

For now, you'll have to wait a year after the date of cancellation to permanently delete the company in QBO.
