Worst service

Saw an ad on Facebook, Samsung A32 with a free samsung active 2 watch. Checked online, nothing.. contacted Vodacom on messenger they told me the special will be the following day.. next day nothing... contacted them again via facebook an they told me it the special will run during that day. Called vodacom and they had no clue about the special... I decided to pay the extra R49 for the watch, no problem.... Contacted them spoke to a consultant (very helpful) she send me a quote to sign.. did that emailed it back to vodacom no reply.. Contacted them again had no records and I again did the upgrade and the consultant said I can choose the colour of the watch. Few days later no communication from vodacom... I contacted them today "your upgrade was canceled" because they have no gold watches in stock. No one contacted me! Told the consultant just give me the black watch and then after a few hours I received a message that my monthly subscription is almost R700 and I have confirmed several time that I want the top up R175 over 24 months. Its now more than a week that I have been struggling to get an upgrade. I think after more than 10 years with vodacom I had enough.
