Bad Attitude from the Superviser Mr Sangweni

I recharged with R12 airtime through internet banking. And when i check my balance i was suprised to found out that my outstanding balance was less than R12. I called Vodacomon111 to query about same and the consultant Miss Tsotetsi wasunable to assist and she called her supervisor Mr Sangweni who had such a stinky bad attitude to me. The only answer i received from vodacom is that i sent out 7 sms to 07365 number and their systemis unable to disclose the full number.i then advised them that same was impossible since my sim card was not even inserted in a device. Further the consultant enquired whether i knew any number that starts with 07365 and i told her that i had my mtn number which is now ported to fnbconnect and the number is***. Obviously vodacomsimple employed incompetence ppl and the supervisor demanded me to remove the last number on themessage centre numberso that my device wont be able to send anymore messages. Really is it how i am supposed to receive assistance from the contact centre? Further more after i spoke they still deduct my airtime. I need answers as to how they treat customers fairly with due delegants? The no. I query about is *** BAD SERVC
