Extremely terrible service

There was a tracking device stored in my ex car and Bike some time back. So he opened the account, and I was only the account payer at the time, however they managed to use my ID number as the person who opened the account. Him and I have been trying to resolve this issue for quite some time now, with no luck, instead of moving this over to the correct ID number they have now gone and opened a completely new account under his ID. The service received from this company is absolutely revolting, they put you through from pillar to post. We now have 3 accounts between the 2 of us, the 1st two rightfully opened, however linked to the incorrect ID. The 3rd one he is under the impression they have moved the accounts over to his ID, which we have just found out is not the case but rather a new account that has been opened under his ID. All I want is this resolved, however I am not getting any luck.
