Pathetic service from Vodacom

I am very disappointed by Vodacom after being their customer for over 20years ,I am getting the worst service ever.I have been trying to cancel my contract since November last year.They first put me on a covid relief which I did not request and they failed to provide me with the call recording after I requested for it.I was then told the contract would be canceled end of Dec.To my surprise on the first of Jan I received another allocation again. I have been told now that I am liable for the invoice as there is nothing that they can do and I need to follow up with cancelations after having had called them several times from October right through November. I am truly disappointed with this ******** company that is abusing black people and I would like to urge people to consider carefully before taking up Vodacom as a service provider. They have let me down.
