Poor Service and Useless website for upgrades

I had extremely poor service from Vodacom today Which is frustrating. I am a customer for 20 years with them. I have two contracts that I wanted to upgrade. Firstly, The upgrade is not possible online or through the app. Secondly I tried to phone in twice. First time waited 20+ min for the call to be answered to be cut off directly after Hello. Second call got answered again after 20+ min to be put on hold for at least 10 mins and then the call went to evaluate the call. Really Vodacom. This is not on. Extremely unhappy customer.
