Bad Customer Service

I ordered an IPhone 6s with Altech on the 26 November 2015. The lady assisting me (Winnie Nkosi) then called to follow up on my on-line order- she did the ITC etc and I also forwarded all the documents she required for the new phone and she promised that she would give me feedback on my order. I have now followed up in excess of 5 consecutive times still no reply. Then one of the sales consultants contacted me after 3 weeks to say my phone has been dispatched had I received it yet. Of which I haven't, she too promised she would follow up with me with the regards to my order. Today is the 14th Dec and I am still waiting without a new phone???<br> <br> Why is the service so bad and its only the beginning of my relationship with Altech. Can I expect even worse if going forward because if that is the case then I should rather not carry on with their service.
