Terrible customer service

I went to upgrade my contract and was told I would be called Monday or Tuesday with feedback as to when my Samsung Note 5 would be arriving.<br> <br> No call received so I tried calling the branch myself, it is IMPOSSIBLE to get through to this branch.<br> <br> They continuously put the phone down or it will ring a couple of times and then make a weird fax machine kind of noise.<br> <br> I need to know when I will be receiving my upgrade ASAP please!<br> <br> Kind Regards<br> Charly
