Contract taken out and dedit order done

Went in to store for the black friday deal on 24 Nov 2017 for the Huawei P10 lite and free P9 lite. I was told they were out of stock at the moment and I could take out the contact but had to wait for the handsets to arrive on Monday which I did. I called in Monday to inquire about handsets and was told no delivery was made. Then I called back Wednesday and was told handsets are on back order. A few hours later the store manager calls to tell me they don't have stock and I have to reverse the contract even though the debits already went off. I am very displease with this poor service and do not want to reverse the contract as I already have the sims and the debits already started also it will now reflect on my credit record that I have this contract which I don't. I hope someone can resolve this issue for me as this is my first time going to vodacom and I am very disgusted by their poor client services. Very unhappy.
