Dissatisfied Customer

I had contacted Vodacom to cancel of my existing contracts with them this would be an early cancellation that i requireD, I was provided with the documents. I had them signed and sent back on 28th September 2022. The secondary number was cancelled on 29th September 2022 but i was surprised that my main number was not i had then contacted them and was told to call back the Friday (30th September) as they are still busy processing it. Called back the Friday only to be told by the consultant only one secondary one was processed and not the main one , it was sent to "back office for follow up to date ( 4th October 2022) its still not done and i am having to call back and forth to get this sorted but the money is received. keeping in mind i have been a customer with them for over 14yrs and this is the poorest of service ever experienced. all attachments is in one email including Proof of Payments , ID copy , Signed contract of the early cancellation (premature cancellation as they call it) . My question is HOW DO YOU ACTION ONE NUMBER BUT NOT THE OTHER. I need this to be sorted as I no longer want to deal with them after this...... EXTREMELY POOR SERVICE also no refernce numbers was provided from that department but the consultants i dealt with are " Nkosi , Lungelwa and Numsa"
