UBER DRIVERS DROPPING REQUEDTS AFTER PICKING THEM UP

It has come to note that lately Uber drivers in Durban pick up your request and a minute later cancel on you. This has happened often to me. This evening 01 Jan 19 I requested a uber from Ahmed al Kadir hospital to my residence when the driver Luge picked up my call the cost was R135, a minute later he cancelled and after the second search for a driver Nhlakanipho picked up the request and a minute later cancelled on me. Then I was requested to request a uber again upon doing so this time I was quoted R245 for the same trip I was quoted R135 earlier. This has become a come occurence in Durban that is why I am seriously considering using taxify as I heard they never cancel on their clients
