Accounts Nightmare!!!

Been over two months with my query unresolved. I get bombarded by cartracks account department from 7am in the morning. They say this is their business hours. They cannot resolve my query in two months but open their business hours at 7am.

Cartrack I have no issue paying you for your services. But please RENDER the services. I will not pay until my query is resolved.

I have even escalated to the 'CEO's office' as per their website and still no traction. I requested that they advise their accounts department that theres a pending query hence why there hasn't been payment. It just seems to fall upon deaf ears.

They also just leave automated replies for everything.
