Dololo service and empty promises but quick to recruit

Last week Tuesday(30/04/2019)called vodacom for an upgrade and spoke to Chris at vodacom online on ********** 4 but later realised that the package was actually not right for me so I called back to downgrade it. Was then told by the consultant that they had to verify something with his supervisor and would in turn call me back. He then called me on Saturday(04/05/2019) to no availability instead of calling again, he didn't bother. Today(13/05/2019) when I called in, I was told by his colleague that he was not yet in but he would tell bim to call at 14:30 which he has not. I then called them again at 16:30 only to have the call dropped by one of the consultants.Has service deteriorated to such at vodacom?
