The worst case of customer service denying a disabled passenger wheelchair and rude customer staff telling " Leave airport - we need to close counter "

The most pathetic and disgusting customer service experience at Melbourne International Airport last night. The customer services team and the ground operational staff is a disgrace. Never again travel with Jetstar. Inspite of speaking with " David " from their customer service center after requesting a wheelchair for a disabled passenger, there was none provided. Inspite of the staff watching a disabled passenger struggling to walk, they did not offer any assistance. On reaching the gate the person at the counter did not let us enter the gate as he would have to do the paperwork again. There was confirmation that the flight was still in the ground and the doors were open. I am not sure if I should upload all video clippings and recordings of the behavior of the staff at the counter as we have all recorded on our iphones. The staff was so bad they did not even have a customer service contact number. At the gate we were told Jetstar would book our group in the next available flight and coerced ( and strong armed with subtle hints ) that we need to go out of the airport and enter Australia again. During the walk back, two staff of Jetstar who were accompanying us that " Jetstar International is a disgrace. I would request and beg Jetstar to put me back to Domestic. Jetstar International is in shambles ". This was comments made by a soft guy at the counter near the gate and another middle-aged old lady who was also part of the customer service team at the gate. On coming out to the Airline helpdesk counter, the PSM on duty - Nicole said that we caused the flight to be late and even threatened to call security to report an abusive passenger. We were told that our luggage was at a different terminal and kept in the open for collection. We could go there and collect our bags. She said that she could not give us any further details and that she had to close the counter. There were 2 other passengers apart from our group of 5 who were in transit from QF and the staff did not even wait to give help to them. They said Qantas would come and sort the passengers as it was Qantas's responsibility. Is this something you expect when both Qantas and Jetstar are part of the same group. Mr. Alan Joyce, any comments as part of your growing Jetstar strategy ? This behavior from Mark and the team at the boarding gate, David - who booked my wheelchair access and most importantly Nicole the PSM who threatened us to leave the airport or she will call the security has resulted in us losing 2 nights of a vacation. Incurring all the cost and hassle and mental trauma. Also the shame of seeing a disabled passenger trying to walk and yet being told that it is our fault. Can someone tell me if it is okay to upload the video clippings of the people involved and the whole incident and conversation recordings here ?
