*****ing my money still even after I requested a cancellation three months ago - Requested for transactions to be reversed they ignore all emails and call me backs

Still three months after I requested for my internet to be cancelled as my service was always down they do not respond to emails or requests to be called back these ******* took nearly R500 off my account and tried for a second amount. I’m sent them emails again requesting they cancel my service as I requested nearly three months ago and requests for numerous call me backs they don’t ever respond. I am a single mother of two and I am in a wheelchair and do not money to waste going up and down to the bank and putting airtime on for my call to only be cut. My best advice to anyone do not use rain not only do they ignore your email they still take your money when you requested a cancellation three months ago due to lack of service firstly and then the lack of communication when you request help.
