Vodacom Sucks !!! Period!!!

I purchased prepaid electricity using the Vodacom App. I used my Vodabucks earned along with a cash payment to purchase a electricity prepaid voucher from Vodacom. I never received the purchased prepaid electricity voucher from Vodacom. Vodacom customer care (Vodabucks department) informed me that the problem was on their side and promised to refund me within 7 - 14 days. Sadly, almost a month later and after numerous calls to them and escalated queries nothing has materialised. Sadly Vodacom is quick to take one's money but slow to resolve issues when they are at fault..." lip service " ..should be their motto !!!
