New contract sim not activated

I app**** for a new contract after beeing away from MTN for a few years . <br> It was agreed the contract would start on the 20th of May. received the phone on monday 18th may . Phoned MTN call center to activate the sim card . Was told the sim card would automatically activate on the 20th between 7 and 8 .<br> Tried to phone the call center again to sort out the activation as it was still not activated on the 21st . But now the call center is on strike and there seems to be no way to get my sim card activated . This service is lousy and i am considering to cancel the contract and send all my stuff back to them . Really angry and annoyed to sit 2 days without a working phone .
