unable to cancel app**** contract

My girlfriend was contacted by vodacom on 21January 2015, she was offered a contract deal for the new vodafone 3G tablet. The person explained to her all the details of the contract, especialy about how she will be dealing with the paper work. He explained to her that she needs to provide the delivery man that will drop the parcel at our house the papers ( proof of residince, copy of I'd and payslips ). And was also told that the parcel will arrive in 3 to 4 working days. So we waited for 4 working days and no tablet. So she contacted vodacom again. They explained to her that she is supposed to fax through the paper work( payslips and ex.). She was not told that and explaind it to them. They then told her that they will cancel the request for the contract. We then went to cellucity in N1 city to get the tablet through them. They then told us that the requested contract was not cancelled and she could not open a new contract untill they cancel the online contract request. By now we are quite frustrated. So for the last four days we have been contacting the cancelations department and was promiced that they will sort it out and every time we were given a different story. Pls contac
