I have a contract with Vodacom which is ending on 15

I have a contract with Vodacom which is ending on 15.12.2026. I went to the Vodacom Store in Cape Gate and asked them the process of transferring the current contract to my son. They informed me that it is an easy process and that my son had to complete a few documents which I had to submit. He then got a quote which were completed wrong and with a contract end date 27.08.2027. He did not upgrade...we just want the current contract to be transferred. After various calls to Vodacom we have not visited the Cape Gate Branch again and they also could not assist me. No-one is able to assist me or resolve my problem / query. Pathetic and very unproffessional
