BILLING ISSUE STILL NOT RESOLVED!!

I've been struggling for 4 months now to get them to fix my billing. Every month the billing increases and they charge me for a watch that I don't even own. When will this be fixed. I can't even log a fault on the app as the app is not working. Really disappointed in this poor service. I've been with Telkom for many years and it seems like the quality of work and service is just decreasing. I haven't even received my deposit back from a few years ago.
