Poor service

On the 2nd of May 2018 I decided to upgrade my cell phone contract with Vodacom . As before I decided to look at packages and upgrade online as this was the most convenient option. I received an sms that advised me a consultant will contact me within 24hours. After 4 days I contacted vodacom online department and asked them what the problem was just to be told they do not have stock and there will be some delay. 2 weeks later I gave them a call again to get an update and was told they still don't have stock. I asked the consultant what is the ETA of the new stock. She informed me that she does not know but will follow up and contact me with an update. At this time I decided to log a complaint with the customer care division. Customer care told me to contact the online department I explained that I have been in contact with them and that they are not giving me an acceptable answer. I later received another sms informing me that my case has been resolved and a consultant will contact me within 24 hours. Again this did not happen so I re-sent my complaint to customer care and again I was told to contact the online department. The latest from vodacom is to blame Sony to be at fault.
