After 3 months, no delivery

I upgraded my contract and I was told that there is a stock issue, being very patient I waited for the stock and after a month, they finally received the stock, now I am waiting for delivery and after another month, no delivery after I made prior arrangements for a 3rd party to take delivery of my phone, it was returned to the warehouse and now again after another week, still no delivery<br> <br> This is bad service and I am thinking of cancelling my contract and move over to another provider<br>
