Vodacom is *****ing my airtime.

I bought airtime for R275 on Monday the 1st of May 2023, i used R51 to buy minutes and 1Gig data bundle for that day only. when i woke up the next day may airtime balance was R160 and i so bought a R29 airtime voucher by mistake, i used R27 to buy minutes and 1Gig voucher. today the 03rd of May when i first checked my balance it was R43 and i tried to buy minutes for R12 i received a message that i have insufficient funds of which i could not believe because i just checked my balance and it was R43 but disappeared few seconds later.

I have been a customer for over 25 years and i am very disappointed at level of service, they are *****ing my airtime, and this note the first time. i have no subscriptions but my airtime is disappearing.
