Contract cancellation

I've been a Vodacom customer for over 14 years, It was very easy when I wanted to add lines into my contract however, one of these lines has reached its end date and I have been trying to cancel it for months now. I initially called in May where the lady I spoke to was more interested in selling me a reduced premium on my 2 other lines than cancelling this line ***. Even after I specifically told her to cancel this line as I am unable to afford it anymore and it is not used. Following months I kept receiving invoices for this number. I called again in July spoke to another lady who wasn't eager to listen to the recording on the May call I made. They are quick to tell you that their calls are recorded but not willing to listen to them when a client requests for that to be done.

I am very disappointed with this kind of service from a service provider that I've been a part of for more than a decade. I just received another invoice and this number is still billed. So entirely I am being forced to keep a line that I no longer require for months since I've cancelled. This is a disgrace from such a big company that they feel the need to make money from people by ******ion.

I want this line cancelled.
