HORRIBLE CUSTOMER SERVICE

WORST customer service EVER! I upgraded my phone online on 26 March 2018 and am still waiting for the phone to be delivered!! I called the customer care several times and each time they tell me the phone is still out of stock from the supplier. I call today (26 April 2018) and apparently the phone was delivered on 28 March by RAM but again no one knows anything about it and i did not receive any device or phone call....NOTHING! And all the consultant can tell me is that they have problems with RAM and she is going to have to CANCEL my order and reprocess it...and then i have to wait another TWO WEEKS! E
