They're a disappointment

They deducted money from my bank account on the 15th, our agreement clearly states 25th of everymonth, granted this is a public holiday, what about the 20th, or after the payday then? i wasted my airtime in their callcentre with everyone asking how they can help, once i ask that the money be transferred back into the bank account, i'd be asked to stay on the line only to be back on the callcentre, eventually i gave up. this is not the 1st time these people do this, and i want to state it on record that they have breached our agreement which means i will then kick them off my bank account, if they want their money, they will email their bank account so i can personally make the payments myself. lastly, the same way i am struggling to get anyone helping me or talking to me, is the same way they will struggle to speak to me when they call in the near future. andikufuni ukugezelwa, enough is enough.
