NO customer service, Contract with no Product

I took my nephew (Dillan Lawrence) to the branch at Southgate the week before Christmas to upgrade his contract and phone, the contract has been upgraded and paperwork done. HOWEVER, we have been waiting for stock of his handset (Samsung S6) now since then. They NEVER ANSWER their landline, and everytime we take a trip to the branch we always get told \NO STOCK"";without a new device.<br> <br> What kind of service is this? Does this even comply to the CPA?<br> <br> really not impressed!"""
