Customer care is useless

Dear Vodacom

You have without a doubt the absolute WORST customer service EVER!!!

I have been trying since DECEMBER to deactivate my 500MB bundle. In-store, online, via the app, and customer care. I was promised telephonically that it would stop at the end of December, yet here I am in March and it is still there. I tried the online chat option, yet that wasn't successful either.

I have tried customer care again, but I get to a certain point and then it cuts out.

Please please tell me what I must do to get this bundle cancelled? I recently upgraded, but am at the point where I will rather cancel all three my contracts and pay penalties, that work with your *********** organisation anymore.
