Unprofessional Manager

I signed a contract with Vodacom a week ago, and the sales consultant sent me a message to say "sorry i have to cancel your contract because my Manager sold your router" is this now how you treat a customer??? Very unprofessional the Manager of table bay mall did not call me to apologise nothing. I have to call them to ask how they can assist me in this matter. The consultant and the manager is playing the blaming game...
