OVER CHARGED ON MY BILL!!!

I've been trying to get hold of Trudon, yellow pages for over 2 months now without any success either by email or phone. When it's for us to take yellow pages products they are so quick to phone but when we have problems there is none that can answer our calls. Yellow pages have been charging me now 2 months in a row for the same thing on my statement which I've paid already which is meant to be 01 of 01 months. Tried phoning Telkom to see if they can fix the error on my bill but unfortunately they can't as yellow pages are the only one's that can correct the over charging on my statements. Getting phone calls from Telkom saying I'm in arrears with my account which is the yellow pages charges and if I don't pay they going to switch me off. I'm not paying for something that I've already paid, yellow pages need to fix this ASAP. Also when you phone their numbers the answering machine says that they working from home due to COVID as per government regulations (thought we were all back to work as per normal since last month) but that doesn't mean they can't answer their phones???? Where is the customer service? From now on wards I will not be taking any services from Yellow Pages as I do not want to go through this ever again running around trying to get hold of them with no success at all!!!!!! This is unacceptable and a total ****
