Do you know what you are doing?????

On the 29 January I upgraded 4 phones on our account and I submitted the quotes with one letter stating the make and models of all 4 phones , on the 02 February only 1 phone got delivered. So I waited thinking they might be out of stock with the other phones. When I phoned on the 09 Feb asking when the delivery of the other phones will take place, the operator informed me that they forgot to process the other 3 phones, put apologized and promised it has been processed and delivery will take place during week. So another delivery took place on the 12 February but only 2 phones were delivered, so when I followed up this morning on when the last phone will be delivered they informed me the last phone wasn't processed and that the quote expired so I have to apply all over again!!! When I told the lady that it is unacceptable and the problem is with their upgrade department and they need to sort the issue out and I will not apply again she hanged up on me...
