I am currently on the line with a consultant that has just put me on hold for 21 minutes i am self employed and need to run my business as i type this complaint i am on hold i couldn't get the consultants name i inquired as to why my airtime balance is on zero she proceeded to check the system and tell me that i was on a call for 13 minutes and my call log states that i was on the call for 1 minute and 45 seconds she then said there is nothing i can do that alternatively i should go into the vodacom shop which i stated that is a inconvenience i then asked if i could possibly email the proof our escalate to a floor manager she stated that they do not have emails and that managers do not take any calls i have been a loyal vodacom customer since before the existence of smart phones and get treated like some sort of child get shouted at over the phone by people that are not qualified to be in the customer care service as i conclude typing out this complaint i am still on hold the total duration of this horrible call is now 29 minutes and 23 seconds this is absolutely appalling service
