Contract Airtime Not Received

Over 2 weeks ago I collected my phone from the Vodacom Store in Vaal Mall. On that day I signed the contract and it was a transfer from prepaid to contract. I was told that I would receive airtime shortly. Later that week, the airtime hadn't come through. I went back to enquire about this, upon investigation it was found that the transfer was made to the wrong number. Then I was told this would be rectified soon. I went to the store again and I was told the request was being processed and I would receive the airtime the next day. 2 days passed and I went once more for a follow up. I was given yet another story, only this time, I was told I would receive the airtime in 4 hours. Today I called customer care and they couldn't help me. I was referred back to the store again. I am spending money going to the store only to be sent back with an empty promise. I have spent more money trying to resolve this issue than what the contract is worth. The 1st payment has already been deducted from my account, that part they didn't get wrong. I am very displeased about this.
