R160plus Air/time data gone twice in 1 hr

Visiting South Africa, leaving in 2 days after 3 months stay using Vodacom, my air/time and data went depleted twice (yesterday/today) in less than 1 hr(first attempt) and less than half day (2nd attempt) on a recharge of both data and air time purchased. Spent several minutes trying to get a hold of customer service with no success on even collecting a call. More than R160 gone without being used. Heard many things on Vodacom and saw people being affected on different ways trying to communicate without a satisfactory solution on similar issues, just being left as customers without being compensated on any way even by being given back the product they intended to purchase for a reason (air time/data bundles). Telecom companies never loose, and more could be done. I don't know as a foreigner now how could I possibly be assisted at 2 days of leaving, still found worthy leaving my feedback on Vodacom and the unfortunate situation of how I will be leaving the country not willing to throw money on the garbage as it has been felt, and not being able to communicate and get satisfactory assistance from the company on any way. Good thing is coverage compared to my lst visit to SA last year
