USSD Service not working,now airtime depleted now

Yesterday the whole day i tried to buy data with the airtime i had but i couldnt. eventualy the data i had ran out and when i tried to purchase data the vodacom ussd service was not working. Sadly i couldnt even afford not to have my mobile data switched off as i use my data during work as we communicate with whatsapp and such. Now i have lost my airtime, lost communication at work and Not even an apology from The vodacom service nothing. totaly and utterly dissapointed and frustrated!
