COMPLAINING ABOUT THE SERVICE OF TOTALSPORT

below is the email i have sent to Totalsport complaining about my uncle's account , he did go to the shop to ask and he was told that he bought a Phone online , my uncle is a very old man who knows nothing about the internet and was surprised when they told him that he bought a phone online, we did sent an email requesting the Proof of delivery that was signed and the ID of the person received the phone , we haven't heard anything from Total Sport up to date. i think what Totalsport is doing to our elders is just not fair, thought i should come complain here maybe i might get help or will take legal action as i do not have any option .

My name is Frank Mabasa and i have an account with Total-sport and have been making payments every month and i recently seen that my balance have increased and when i ask they gave me the mini statement saying that i bought something Online worth R899.00 on the 06/06/2018 and according to my knowledge i have not bought anything online as í am not fami**** with all the internet stuff. i am not happy with the service that i got as i was told to do an affidavit, open a case and fill the dispute form, as old as i am i feel like i didn't get enough information on how to go about the situation. i wasn't told what exactly did i buy with that amount but yet it reflects on my statement. Kindly find the attached documents and i would really appreciate if i can get last month statement showing all the amounts (details) .My contact details : ON REQUEST card no:ON REQUEST
