Bad Service

Good day

I done a upgrade on my phone and the manager at the store told me that i cant get that opsion any more i must took another one. I ask him more than one time will i loose my R1800 airtime that is on my phone and he told me no. He done the upgrade to the bigger contract and signed nothing and i wait for almost a month now for my handset. Every day it is another story. Yesterdag all my money disappeard from my phone. I phoned voadacom customer care they told me that if you upgrade you lost your airtime....so what tey actually told me is that if i bought n 2.5kg suger at pick a pay and i only used 2kg pick a pay come and take the other 500g back on month end. I still did not even received my handset my they took my airtime.... Vadacom i want my airtime back and my contract back to the original contract because io misconduct from your people.
