Dissapointed and Livid

Worst experience with this company I don't even know why it's operating their service is extremely alarming and they are ****** ???I have a debit order in place but they fail to deduct even though there is funds on my account. In July they did not deduct I spoke to a consultant yesterday asking me what is the reason for not paying? Really ???today they send me an sms saying i'am in arrears of R320 now I'm asking myself how did they get to R320 when they did not deduct for 1month. We try soo much to keep our credit right on track but companies like these fail us ?i'am soo upset and angry
