Greyhound stole my trolley bag!! I want it back!!

I'm so angry, can't even type this review properly. My trolley bag is still with Greyhound/Citiliner, full of my shoes and I'm suspecting they have ****** it. I have called and emailed Greyhound since the bus left with my bag on Sunday morning at Parkstation, headed to Pta. I called their customer care line, sent an email and four days later, still no response. This morning, their customer care line says 'This number does not exist.' I feel like I'm in a twilight zone and Greyhound is a ****. Having been loyal to their brand for years, I truly cannot believe their lack of care for people's belongings. Mine is not the only story but I will make it known that they are useless and inconsiderate to their clients. Now I have to go open a case with the police because that's all my shoes in that trolley bag. I gave them all the information they needed but they chose to ignore my case. I'm so disappointed.
