Failure to resolve incorrect billing

Never in my life have i had to deal with person as rude and *********** as the Area Manager named Pensive Ndlovu, who instead of resolving a complaint at hand she makes it a personal issue and wants the validation and very begged to do her job as an Area Manager. Despite fighting for months to get TFG to reverse the charge for a cellphone that she returned as she did not only order it but also did not want it, now I'm going back and forth trying to get them to remove the miscellaneous amount of data to the value of almost R1000 when she did not even utilize that sim card. On the 05th of October 2021 I spoke to Abongile from TFG Connect and he advised that his Manager Michael would give us a call within 24hours, however 10 days later no call has been received from the Manager, yet each day my mother who is 71years of age and her health being frail is being harrassed by a lady who keeps calling her from the number *** and whenever my mom tells her to speak to me (her daughter) the consultant hangs up the phone. I escalated the issue to Pensive Ndlovu and her response was "the same way you looked your complain send it to that email address" and she dropped the call on me. What kind of a banana company is TFG running and is it part of your mandate to de***** and be rude to your loyal customers. I will? Your lack of empathy and failure to resolve this issue which was caused by one of your agents who **********ly proceeded an unauthorised sale of the phone to my mom whole she was sick is appauling to say the least, all because they wanted to get a commission. This is ***** and instead of TFG condoning this kind of behaviour they seem to approve it. This company sickens me.
