Poor service unfilfilled promises

I joined Vitality Health, told 1 month free, but then got double deducted in December. I complained. They first had to listen to the tapes. When i phoned back they confirmed agent error and would refund. Problem resolved - NO. Phoned in Jan. Started the whole process over again. Spoke and repeatedly explained to Ipimeli, lisa, Jade, lieth at billing dept. After hours on the phone it was again confirmed it was due and would be paid shortly. February nothing. Phoned 3 March spoke to Mbali she said nothing was due. Checked details phoned back spoke to Chad explained the whole thing again. Got cut off. Phoned back spoke with Siya and sindy explained again and had to again argue the whole issue eventually spoke with Purgan who then confirmed escalation was done on 22 Dec and would resubmit - wait 3 days. Two weeks later still not done. Spoke with Jacklyn promised a call back - nothing. Phoned back next day and had to start explaining the whole process all over again with Lindelo, Nicole, silindile - got cut off 3 times. Eventually spoke with Sethu and then Theo who confirmed - agent error, flag to be loaded on vitality side, i must wait 6 days. Asked to speak to Vitality directly but got cut off. Gave up - will see in 6 days. Absolutely infuriating - empty promises.
