Contract sales communication

So I've been trying to contact cell c regarding a contract phone that I took out a week ago. The customer service agent told me the verifications department will get in touch with me to verify my delivery. I haven't received any communication from them. I haven't even received confirmation about my contract that I took out. I gave out banking details and debit order date but no phone and no contact details has been sent to me. When I do get a hold of customer service they say that there are notes left on my account stating that they tried contacting me which is a TOTAL LIE. When I try canceling they tell me the agent that did the sale with me will call me back. I even went in store and they advised on their side they can't do anything. You guys are useless and I'm regretting that I even tried you in the first place. Funny thing is my friend app**** at the same time I app**** for my contract and she app**** by Vodacom her phone has been delivered already.
