MTN CRESTA SHOPPING CENTRE: VERY BAD SERVICE

Requested early upgrade due to broken handset, waited 6 working days for retentions to authorize (they promise 3), got reference to take to store, MTN Cresta Shopping Centre had stock, went to store on Sat 3/10/15, Salome assisted, even with e-mail and ref from retentions in her hand she struggled for hours to get it done, 5 references were given before she completed the job, got no copy of my contract!. A nano sim swap was done and minutes after I left store my existing sim was deactivated, she said 24-48 hrs to activate new sim, needless to say that did not happen, after numerous 808 calls over weekend I was told all is active and must go back to store, went to store yesterday, David assisted, checked system all active, did a \push message"and said to wait 3 hours tops. Nothing yet"
