Avoid Virgin Mobile like the plague

I dont know where to even start with this complaint, last week Thursday my wife called Virgin Mobile to upgrade her phone, she was then told she qualified for the iPhone 6 - Banele Mabena promised to place the order on the day and we would have the phone the following week, then we received a call saying no things had changed my wife needed to be vetted first and then they would advise, Monday morning comes and goes without feedback, we follow up and are told by Andrew that we can get the phone and were approved on Friday, Andrew then promises to place the order and that we will have the phone by Wednesday. Wednesday morning and no sign of Couriers so we phone and follow up, there is no order in the system and there is now no stock of the iPhone 6 so we then take the Samsung 6s and they place the order for the third time - 45 minutes later we get told that contract type is not approved and we need a top-up contract so we take a Samsung A7 with the promise of the order being place and delivery and Friday. Surprize! Friday is here and no phone and missing order again. There is never a manager available to escalate the query and the agents do not know how to use the system. Pathetic
