1-Grid shocking service

Their Accounts department/system is so unorganised its painful for me as the client.

They have continued to invoice me for services I cancelled in Dec 2019. When we refused to make payment based on the fact that the services had been cancelled they threatened to blacklist our company and suspend the other services we had with them. So we proceeded to make as we could not afford our other services being suspended.

I them had to follow up on the incorrect invoicing for the services we had cancelled. Finally they admitted the error and offered to refund us, but only for 2 months and not 6 months. When I queried why only 2 months, they ignored my query and proceeded to tell me that the 2 month refunded amount was available on my credit facility and that I should advise them to which invoices I would like to allocate the credit.

On top of this, they send me a new invoice in June for re-activation of services (the cancelled services). It totally boggles me how *********** the accounts department is.

Am I ever going to get the proper amount refunded?

This is not the 1st time our invoicing was incorrect.
