Cell C bad service

3 weeks back I got a call from Cell C promoting something which I was not interested in but interested in upgrading as I have received an sms saying i qualify for an upgrade on my current contract. I told the Cell C agent to assist me with upgrade and she did. On the delivery to my surprise I received 2 sim card and only when I called Cell C to activate the new phone, I was told its a new line that means I had 2 contracts. I returned the phone and cancelled that and it was sorted. Now I am having problems with whatsapp and facebook since I got the new phone, I bought data twice thinking i didn't have data only to find out when i called Cell C to ask about it, then they told me i bought two shoutout data and they stopped my whatsapp and am going to forfeit the one data. I have been calling Cell C to fix my problem for 5 days now and still no assistance.

Am really disappointed with their service and wish it was not too late to cancel the contract.
