Account system sucks

My mom that has been a client of Edgars since the 1960's received a letter re. account being suspended due to a lack of payment. This is after she had to get new glasses and was informed to put it on Edgars account - done deal helps for pensioners. Made payments every month and made payment arrangements at Westgate - No record of such. I contacted their urgent correspondent no ***to speak to Ms Johnson - was informed no one was in the department but I can email the query to Ms. Johnson and Ms. Molelekeng - this was done 23 and 24 February - still no reply. Only letter in May informing my mom she will be handed over and blacklisted if the full outstanding amount is not paid immediately. Beginning of June went to Edgars - borrowed money and gave them their outstanding amount of about R1000 and informed them to close the account - as it seems they do not need customers - in this matter long standing customers with good payment history. THANK YOU MOM YOU ARE FINALLY RID OF EDGARS WHICH IS FULL OF PROMISES BUT CANNOT DELIVER A SERVICE. Thus the reason I don't buy from them as I struggled with their incompetency on your behalf
