Contracts

Good day I am currently at my wits end trying to help my father get this issue resolved. So my father app**** for a cellphone contract with vodacom and explain to them that he wants to keep his prepaid number. They sent out a new contract with a new number and when my father received the phone and realized this issue he requested for the contract to be canceled and had the device collected with their courier within 7 days cooling off period. He was told that it would be canceled and that he would have to reapply for a new contract again if he wishes to use his old number like he explained in the first place. The device has been received by them and there has been no usage on the device however it is still jot canceled and now handed over for collection of over R14000. He is being harassed for this money that he is not liable for and even after countless calls and emails to vodacom regarding this the issue is still left unsolved.
