Terrible service from Absa

Terrible service from Absa Credit card missed payment. I have raised issue with Absa related to sms notification sent to me showing amount that i need to pay for my credit card amount being send on sms is what i have paid and i have been getting sms since being client and paying amount reflected on SMS. Now have missed payment affecting my credit report. I was informed what was SMS by bank is incorrect amount. It happens next month received sms and likely pay more and it was not same amount on sms and email. I have logged complain with Absa closed without being helped. last spoke to Absa customer care team leader even now no assistance. Need my credit profile to be fixed.
