Unknown upgrade

I app**** for an upgrade in Oct'15 for a blackberry Z3. I was called and told that the Z3 is no longer being made. I was then told I would receive a blackberry classic. Upon delivery I reveived 2 phones. I called in to advise Cellc that I received 2 phones and wanted to know why. The agent I spoke to could not answer. I asked if I shoiuld return the extra phone and I was advised to keep it.<br> <br> This month I received an SMS for an upgrade on my other cotract. I app**** online for the upgrade and later received a call to advise that the contract has already been upgraded. When I ask when I was told that it was done in October with my other contract. Nobody can tell me who authorised the upgrade and why I was told that the initial upgrade was only for one contract. <br> <br> I am really unhappy with the service I have received from Cellc after being a loyal customer for so many years. I believe this to be a breach of contract. I will ensure that I take my complaint to the furthest level. I have already spoken to about 8 people and each person has no record of my previous converstion. Very frustrating.
