I am physically begging Vodacom to take my money and still they wont

On the 10th of February I attempted to migrate my existing prepaid number to a "data contract". I tried to do this in store but the agent told me that the online deals are not the same as the in store deals. I was told that if I want that specific deal I will have to apply online....which is what I did that afternoon. I app**** online for the deal that I would like and before I knew it I was approved and realised that on the website there is no option to choose an existing number/sim and that there is now a new sim card on the way. I phoned Vodacom and explained that it was a mistake and that I am NOT looking for a new number. I want my prepaid number on the contract. I was advised that I need to cancel that sim card and start the process over which is what I did.(Ref ***) I was then told that the cancelation will take 24 hours to conclude and that I need to wait for the cancelation before I can apply for the contract with my prepaid number. Two days later on the 12th of February I received an sms from RAM couriers telling me that my new simcard is on the way. I was very surprised because I has canceled that contract. much to my disappointment the cancelation did not happen as promised. I phone vodacom and was told that I need to wait for the couriers to deliver that sim and then tell them to return the sim card to vodacom, again which is what I did. I was also told that untill the simcard is returned I cannot cancel that contract and need to wait for its arrival back at vodacom. While all of this is going on I am also not able to apply for the contract that I want. Which is hard to understand, but fine I waited patiently for the sim card to get returned and that cancelation to be concluded. on Friday the 19th I received an sms that order K*** has been returned. Today the 22 Feb almost 2 weeks later I phoned vodacom again to try apply for the contract I want, I am now being told that the lady (Londeka) dealing with my contract is on leave and that no one else is able to process my request. This is ridiculous vodacom, how on earth can you operate a company where only one specific agent can deal with a customer's request. I am now tired of begging you to take my money and sign me up as a customer.
