If terrible service had a name it would’ve been hertz

It’s disgusting and pathetic the service that hertz gives you , ive returned the car I hired exactly a month ago and to date my deposit has not been refunded .. I’ve sent emails and WhatsApp messages even Call the call Centre all they say is they’ve sent the bank a letter and it will come .. initially before hiring the car they told me the deposit will come within a week or so then on hiring the car at the counter they told me a month with a debit card ... I’m very doubtful of hertz and their service and wouldn’t advice anyone to hire a car with them if this is the service they have to offer
