MRPMobile - worst customer service i have ever experienced

I settled my Mr. Price Mobile account in 2019, however, Mr. Price kept on billing my account for the next 34 months, after sending them the cancellation and settlement POP. I manually canceled the debit orders, because none of the call center agents that I spoke to could assist me, now I have collection agencies contacting me threatening with lawyers for something the very company they are representing did wrong! I have called the call center over 17 times and have an email trail dating back to 2019, but all Mr. Price continuously say is that someone will get back to me.

Honestly, this is beyond horrible customer service, I have not experienced anything like this in my life!
