Vodacom u are really bad in service

hi

i app**** for a vodacom contract on Thursday. all was approved n good. Sunday i phoned just to confirm that i took the 32gig phone and not the 16gig phone and the agent on the other side said please have your phone with you from tomorrow because they will phone for delivery arrangements. I kept my phone with me at all times. Even when i was not available i gave it to my daughter and told her pls if phone rings you immediately bring it to me. Today i phoned again to see when they will deliver and i was informed that my contract was cancelled due to the fact they could get hold of me. They had my phone number with them to get hold of me but phoned other numbers i did not have with me. i feel very angry and upset when i then yet again phoned Vodacom to reapply, when they told me i dont qualify now because i got a low vodacom credit score now. is this right?
