CAPITEC BANK CHANGE THERE SMS NOTIFICATION NUMBER, WHY?

Why is Capitec Bank changing the SMS notification number? If you receive messages from the Bank you know that all your notifications is coming from one number but last month I realized that al of a sudden my notification SMS'es was received from 2 different numbers. I already know something is wrong and I needs to keep an eye out.

Now one of my debit orders was run with the wrong amount, RCS and why. They are a financial institution and should know better but the fact that the Bank is changing there notification number is a concern to me. Are you all in alliance which each other. I know there are a lot of old people out there which Companies are setting up as they don't check this.

I am not leaving this as RCS is charging me double as they took the wrong amount this month and they did not stay with-in our contract terms. If the bank wants to play games with RCS then they also need to be liable.
