Dubai Taxis - Appalling service from Mirdif

Ive been incapacitated over the last 10 days and cannot drive or walk properly. Pain control are my words at the moment. I have been using Dubai Taxis for the last few days to get me to and from the hospital however on every occassion the taxi has either been so late or not shown up as my booking has vanished into think air, etc. This evening after arriving late from the hospital, an a mere 8hrs before I need to leave to get to the airport, I ordered a taxi to get my essential (cat litter and food) shopping sorted before I pack - I havent packed earlier as I wasnt sure until todays tests if I was allowed to fly. The taxi was ordered at 915pm, and after several calls and even ordering more taxis to see if ONE would show up, I went out to the street to flag one down. I ended up walking from Shorooq to Uptown Spinneys with my bad back, right hip, numb leg and foot. Not happy. Several taxis drive past me so there were taxis picking up in Shorooq, just not me. I nearly drove but since that would most likely end up with me smashed into something else, I decided against it, but I was close. I did my shopping and even bought one of those shopping wheely trolleys, had my trolley packed for me and I hobbled to the taxi rank. Annoyed there were 3 taxis waiting, instead of picking up my booking, I took one and paid him AED20 tip and hope he told his mates. They missed out. As I arrived home a few moments ago at 11pm, I received a taxi call telling me he was outside. I told him I had waited for nearly 2 hours then he hung up, didnt even wait to see if I still needed it and I wasnt even raising my voice. Ive made a complaint with the manager on duty, and as I have a 5am taxi booked for the airport tomorrow, he will manage this booking and ensure that I reach the airport. Ive also requested an investigation into the last 6 taxis Ive ordered over the last 2 days have all been min 1hr late or not showed or been cancelled without my action. If someone else has been picking up my taxis from Shorooq, you know who you are, then again you wont care if there is someone in pain who needs that taxi more than you, and you most probably wont be reading this. Sorry, I just had to get that off my chest before I clean, get the kitties sorted and pack. Perhaps an hours kip wouldnt go amiss either!
