pep should treat their customers properly

Hi this store accounts department & its the company's policy to harass customers I'm a new pep account holder the used to send messages to open an account so I tried & it was approved I didn't bother too much until pep continued sending messages to go to a store with my ID & activate my account so I did that to get them off my back then they messaged me to use my account coz you have this amount to spend then 1 day my wife said listen lets get some stuff from pep. we went to pep twice & used the credit not much just a little now a get a message on 11th August amount due R? payable by 30th August so I got onto the app & downloaded the statement & I was happy with it & now on the 16th August I get another sms saying you amount due is payable to keep your account active now I'm confused is why it becomes payable so soon in the middle of the month. I sent an email to them but they never responded & now yesterday 17th August a lady phones me & it looks like a cell call 072...... & you know the bla bla bla talks asking me hoz my experience with shopping with pep ... I just ignored her & asked what she wanted & her story is do you know your installment is due by 31st & how would you pay .. in-store & which store you going to make payment ... you can make payments at Ackerman, tekke town etc & you can shop at these stores with your pep card now this is not on coz I had much bigger accounts with no hassle at all I know you have 7 days grace to pay your account & if you late the company will either call or message you not harass you everyday when the installment is now even due for another 2 weeks overall I'm having a hard time trying to understand how pep works now I told my wife as per this invoice I'm going to pay all the account at once & close this account with this pathetic company period
