Constant problem with loading of new contract

I took out a new contract with MTN on the first of this month (May 2015) and to date my cell phone is not active. I took out the contract with the istore at the Pavillion but the problem is with the network itself. <br> They initially loaded the wrong package on my SIM card thereafter cancelled it after I had informed them of the error. They then proceeded to load the correct package and told me it would be activated overnight and yet this has not been done. It is now the 11 May and I have a phone with 'no service'.<br> I'm frustrated and very irate at the complete lack of knowledge and service with MTN
