Deposit after one week not paid back !!!

Good day

Had my first rental experience with Tempest Car Hire when I went down to Cape Town from the 13th till 23rd of November. Returned the vehicle on the 23rd of November before 12h00 the Afternoon. I am still waiting for my deposit to be paid back into my account. It has been more than a week. How long can it take. All my other rentals through Avis and Europecar the deposit is back within a few days after returning the rental car. Terrible service from the call center as well - keep putting you through to someone else and then it just goes to a voice mail. Also they don’t reply to ANY email inquiries. I am very unimpressed and will NEVER again rent a car through them. Cannot believe Vitality associates themselves with this poor rental company.
