Shocking service from Budget Car Rental

My latest experience with Budget has been appalling. I left my mobile phone in one of their cars when I returned it at OR Thambo Airport. I realized it once inside the airport. It took me 2 hours to try and reach them as I traced the phone and could see it was with them. I eventually had to phone their head office who then got hold of them on my behalf. By the time they eventually phoned me I was at the boarding gate about to board a flight. They undertook to keep it for me in their safe so that I could collect it when I returned in 2 weeks. I received written confirmation with a reference number. When I returned to Johannesburg on 8 Dec I immediately went to lost and found and my phone could not be found. When I informed the lost and found person that I would have to report it to the police as it is a company phone, he verbally abused me. I was told they could only speak to the person responsible on Monday 10 Dec and they would phone me. As is to be expected no one phoned me. I had to again phone the head office to try and get hold of Budget as it is impossible to phone them. Even their head office acknowledged that they are difficult to reach. I was later informed that my phone had gone missing and their management would keep in touch with me. That is it. No offer to replace my phone which was clearly ****** by one of their staff members as they confirmed to me that it was held in the safe. I would not recommend that anyone do business with them. No customer should be treated in this manner. It is a disgrace!
