******* customer service when your account can't be handled correctly!

I have a Game my store card and I get my statement emailed to me every month, and I am registered on their app as well and every month I go in the amount on the statement is the same as on the app. Every month I pay as soon as my salary is paid in which is before the 1st there was one occasion which I didn't and it was because their app was not working. But every month I pay exactly the same way. Now again the app was giving a problem yet I paid even more than what was stipulated on the e-statement and on the app and I have the statements to prove it. I get a call saying that I have not made any payments since May, this is absolutely shocking service because everytime I make the payments I get an immediate SMS thanking me for my payment and yet now I am told my account is in arrears by over R2400 this is absolute ridculousness. As well when I do get some credit available I make sure never to exceed the limit and when I look again I get a message saying I exceeded my monthly credit limit it will be added to my next month's installment. Today the young lady that called me when I told her I will email her the statement showing that my account is not in arrears at all suddenly said that their computers are down due to loadshedding and she cant assist me, this is very convenient I worked in a call centre and managed a team how are you able to call someone do the verification process and then suddenly not have your computer availbale to continue the process? Why call in the first place if you know loadshedding is going to happen 5minutes into the call and surely RCS should have backup generators for their call center computers? This is a faulty system because the last time this happened my account was by no fault of mine suddenly ITC listed is costed me to go to their customer service center get a letter to have it revoked which took 2-3 business days take that to my bank it affected my perfect credit score! I think its time to close this account because its more of a nuisance that anything else!
