The service is unbelievably poor. Logging a complaint has no purpose

Logged a complaint and they even failed at this. 2 days later and still have not received any acknowledgment of the complaint. No contact from the escalations team. And no communication from the relevant division manager. If Zandre and Charlton are the best you have, you may as well close down and save yourselves the reputational risk. They have no regard for customers, nor any regard for basic customer service
