Upgraded contract and paying with no device in my possession since April 2016!

Velocity called to upgrade my MTN contracts APRIL 2016. Received a samsung galaxy instead of the edge, returned it 2 days later to the mtn store in westgate as per velocity instruction, service consultant at MTN is Dineo(she is the only constant in this picture), called velocity, mtn and cci for an update ever since April 2016 to date, the phone was then collected by CCI thiss year August 2017 who took over from Velocity. Numerous calls with Velocity, MTN and CCI all promising to resolve and get back to me and NOTHING to date. while i am paying for a contract an NO DEVICE!!!!!!!!!!!!!!! can someone take accountability for this and sort this out from MTN.
