Fuel is never available at Caltex Malanshof - Randburg - what is the point of being a Petrol Station?

The Caltex at Malanshof, corner of Phillip le roux and Hans Schoeman is always out of fuel. they probably have fuel at least 2 days of the week. This is really inconvenient and I am forced to fill up at Engen. I have lost out on my U Count rewards points due to this and want to be reimbursed. the Garage is also always out before a price hike, very convenient as well. The staff at the garage also have no idea when fuel is going to arrive and you are forced to check on a daily basis Caltex at Malanshof sucks big time, please sort this out or you will be losing a customer as Engen always has fuel and is more busier than Caltex
