Extension of contract term in error.

I am very disappointed with service I got from Vodacom, all departments have failed to assist me accordingly since in April 2024 up to today’s date. I have spoken to multiple consultants and team leader who would end the calls on their side after being on a call for a while with them. On the 30th July I called in and spoke to Team leader from retention desk by the name of Cris for follow up on my refunds that was logged on 19 July 2024 and prior to that the was cases that were logged but whenever I do follow up am not being provided with any details. Cris promised to do follow up and contact me back, I waited to 3rd August to demand the update of my refunds. Still the was back and forth with no answer or solution which I do not understand why it takes so long, after having a long call with Cris and promised me that the back off consultant will contact me either on the same or the following day which never happened, I was surprised when I noted that all my numbers with Vodacom have been blocked due to the fact that I have been calling frequently which I do not under why it need to be blocked as am the customer and am doing follow ups on the incompetency as and poor service that I have been receiving from unprofessional leaders. I am now setting with no hope of assistance with my case, and my last option is close the account with Vodacom and move to better service provider that will serve me with better interest. I cannot allow my rights to be violated this way. Sadly, I upgraded one of my number to 36months contact, but as I am speaking the is not even user friendly which It impact my daily work productivity. I took LTE Home router which it give problem of poor internet mostly afternoons from 14h00, since last week Friday I have been working with no internet access. My work space only allows me to work from home as I am fully working night shifts. I cannot even do call to log faulty of the number due to my number have been blocked on Friday after I spoke to Team leader Cris from retention desk. Vodacom you have left me with no hope and empty promises.
