Couldn't handle request of switching internet package

I requested to switch packages to another promo package before the end of the year, at that time consultant told me everything was done and it should be effective from the 1st of Jan.

However I couldn't feel the change of internet speed and when I checked on mweb portal today I realised nothing had changed so I had to call AGAIN. Consultant said they could see the request was logged but she couldn't explain why no further action was taken. So she said she would try to push it today after I explain my situation, I app**** to switch package cause I have guests coming.

Now it's the end of the day, I had to call again and the other lady said it would take 5-7 working days to get effective.

This is very disappointing, switching a package seems a very difficult task for their team to be processed..
