Standarb bank Mobile

i have Standard bank mobile sim, i connected for months without issues and everytime my airtime is finished i had to top up with my own cash which was perfect.

last month i did not have airtime and they said i used it as data which resulted in depleting my airtime and i waited for a new month to be credited and on Thursday i received sms that i owe 1511.99 and when i ask they said i used airtime and requested proof of statement which they cant provide.

they said system allocated me extra airtime. i never requested for additional airtime before which is the reason why i topped up my account with my own money and all of sudden system automatically allocated funds and now i have to pay for it.

i called call centre on Thursday at 3pm my reference is ***.

i will not be able to pay that amount, system should take thier fault if indeed happened as i never requested such.
