Disappointing Awful Parking

What's the point of having one contact number and a set of instructions to call you 20 minutes before reaching OR Tambo international airport, if YOU don't even answer your phone? I've never been so disappointed and highly frustrated. Then to have YOU call me when I'm already at the boarding gate sling if I'm still on my way, yet YOU didn't meet me at Level 3. I ****** called YOU 5 times and even sent an email before leaving my place which is 32 minutes away to tell you I'm not getting any joy coz nobody is answering. Then YOU are gonna gaslight me saying you had a problem with your number and asked if I didn't contact you on the other number... What a joke!!! Your website only has one number and that's the only number on my reservation with YOU, so for you to tell me about your problems with your number yesterday then I was supposed to contact you on the other number is ridiculous!!!
