Disgusting customer service

I am disgusted with Telkom mobile customer service. I spoke to sibusesu at 09:20 Tuesday 17 feb. He was rude and arrogant and when I requested to speak to his manager he transferred me to the que. However thats not my main concern. My contact expired December I was told to leave it running month to month and I will only pay R99 as telkom deducts the device. December I payed R99 I was happy then January my bill showed R700 on quering it I was told telkom charges extra for your data bolt on as I get 5gb with my contract. I was told to cancel and they refunded me. I cancelled on 18 jan told it takes 21 days. When quering today I was told its in wrong que and they have to transfer it to right que and may take 21 days thats disgusting that someone in your company is making mistakes and your customer must suffer. Also the 5gb I was told will be credited back I am still waiting for billing department to contact me as its almost end of month. This better be resolved shortly as even call backs offered by operation managers sheldan Durban branch and Aldan Joburg branch is fruitless
