Disgusting service delivery

Went to Vodacom store Voda world on 21 Dec 2020. Upgraded a specific data contract. Consultant upgraded another contract of mine (voice contract). I saw mistake only on 05/01/2021 as upgrade processed on 31/12/2020. Called Customer care, was referred to call at the store where I upgraded. This is when all the fun started. Lets go back to first visit. Wish I had a job there. Each consultant have a monitor in front of them as well as laptop on desk. This is when one really notices the reason why mistakes are made. I observed consultants checking their Facebook, watch Youtube videos,etc. And the customer is sitting in front of them waiting not knowing what the consultant is doing between the two computers. So called there today, and same attitudes. Consultant is not keeping customer fully informed during the process. Initial impression was that the upgrade will be reversed. Nobody mentioning any time frames. Only informed after waiting for almost an hour, the cancellation will only be effective at month end. Meantime no airtime on the number being used daily, instead data that will not be used. Only communication received was a reference number that is being escalated. As custom er, it does not say anything about cancellation. Eventually asked the "manager Andile Fusi" to give me what is happening in writing. Only got some proper answers after leaving the store and sending the manager an email. Totally inconvenienced customer have to fight to get direction. The manager, consultant, etc does not care that the customer have to drive 25km to the store and spent valuable time trying to rectify their mistake. ps Vodacom the ref no is ***. My tel no is ***.
