Incorrect billing / charges to edgars account and no response

Edgars a ******* to its consumers this is my second post - no response from edgars other than demanding payment - **************** I have always made payment to my edgars account and to my knowledge and previous receipts upon payment at the stores or the easy pay number Edgars provided, my balance was very small. Up until I've been receiving SMS messages and an email about RCS group handling the accounts I then found my account to have an unusually high balance that is being asked for settlement along with a statement that makes no sense !!! It seems to be showing purchases I never made and on a 36 month plan? When did Edgar's ever sell items on 36 months and how did my account change from the times when i made payment and the account was almost settled? Then lockdown happened and now purchases made during lockdown? The call centre agents call to ask me to settle this ridiculous statement but cannot seem to be interested to assist me in explaining how my account arrived at the figures they are asking for, they turn out to be rude and disconnect the call!! Pathetic poor service from the edcon group!!! Customer service poor. And **************** all at once with unnecessary charges on my statement!! What do I have to do to get an explanation to this aswell as on top of that they seem to have charged me for silly insurance products that I never requested. Together with 36 month purchases I didnt make. All customers should check their statements carefully as at times like these we cannot be **********. Further it seems to be another major problem trying to get in contact with Edgars as the queries number provided disconnects.
