I want my money back

I mistakenly bought a month to month fibre instead of a month to month sim with cell c on their website and paid for it then the next day I call in to cancel the application spoke to Eric he advised to send through proof that my payment went through....I did then he advised that he sent through the requests to the admins team and his still waiting for the ref number later on Eric sent me an email stating that I have to call in again ask to be transferred to the ccd department and do the cancellation and that's what I did this morning spoke to an agent Tendai who was not helpful at all I asked to be transferred to a person who will be able to assist me instead he dropped the call. Called again spoke to Themba explained the problem then I asked to speak to a Manger but instead he dropped the phone. Called back....Your agents advised that my application is still at data capturing stage I dont understand why am I being forced to have this fibre line with you guys I don't want it I
