****mers/Incompetence/Intentionally difficult to communicate even

Bought a shirt from Edgars for R150 on my "6-months No interest" account, in the 1st week of April. A month later, RCS sends me a letter of demand for R171 I must pay today. This is ridiculous! So from paying of an amount of R150 over 6 months, the 1st payment is R171... This amount does not even correspond to the official Edgars account I got... Is this a ****mer or legit company or account...? Then I tried to email them to their "Reply to" address - then only to get an automated reply that "this is not a monitored email account... " How stupid is that!?!? And there's no other email address listed on the email or the attached letter... There's not even a name below - just a signature scribble with "Your customer services team" below... That IS NOT CUSTOMER SERVICE! That's hiding from simple queries, behind automated services & not taking responsibility for the incompetence or errors! And I'm NOT wasting my cellphone airtime on another automated answering service where I have to spend money to listen to YOUR advertising for 10mins before even talking to a human being!
