Zero Customer Value :-(

15 Dec 2015, I made an early payment of R2132 to my account. Received a statement for an instalment amount of R84, ignored it as i already paid more than the required amount. January i receive an sms for an outstanding amount of R84, ignored because i made an early payment and more than the required amount. Tried using my credit card and a wonderful surprise, they suspend my card for flippen R84. 99% of the time my account is paid with more than the required instalment, do you ever call me to thank me for paying more than required, NOOOOO, but you so quick to suspend my card for a measly R84, less than flippen R100. Is this how you treat customers with exceptional payment records? Have i ever missed payments on my account? Did you look at how many years i have an account with you, or do you treat good customers like rotten potatoes. So i received a lousy apology via email and all you can say is sorry we suspended your card. I don't think that's good enough....I will shame you on every social media platform that i can. Despite me paying you R2132 prior to statement billed, that should of accounted somehow for the next due amount!!!! Clearly there's no customer value here....
