Stop deceiving us

my contract was due for an upgrade, went to cell c festival mall kempton park Gauteng, took a wi- fi router was told my router will be activated on 2018-07-01 to my surprise i couldn't connect , checked the balance only to find that data is 0.00 called the cell c customer line i was told that the router will only be activated in November, called the kempton park branch spoke to the consultant who helped me, he took my details at 09:30 and promised to get back to me waited and he didn't call, i called again at 15:30 he said he is fixing it and will call me to tell me that everything is fine even now today the 3rd july 2018 10:06 still waiting for the call, i called them now again the branch number is on voicemail. i was deceived and now they not taking or returning my calls. im taking back their router and cancelling the contract and going to more reliable and transparent service providers
