Vodacom Rude Employee for Upgrade

So my wife phoned the upgrade department today to upgrade her phone and we had the unfortunate experience of dealing with a lady by the name of Lindiwe, first of all her whole approach was very rude and not friendly as well, we called cause we needed help to understand the deals and my wife was asking her about it, she did not seem interested in helping and wanted to know if my wife knows what she wants, so she said she seen a Samsung S20 that she is interested and this lady tells her yes but you have a LG, so she must tell her what she wants, so I jumped in to say can she tell us what deals are applicable for the S20, she instantly went off at us that there is someone talking in the background and she can only talk to one person and it was said in a very rude and unprofessional tone, my wife did apologize but she then went on to cut the call before I could grab the phone cause I was highly ****ed off, is this the sort of people you employee to bring or retain business, we then had to call back and we had the pleasure of dealing with Mellisa, which was a chalk and cheese effect cause we came from aggressive Lindwe to sweet Mellisa. Sort you staff out cause you could have a lost a deal, we are loyal to Vodacom and have been with you guys for years, but this is not the first we had to deal with employees who are rude and aggressive in their approach and the day is going to come when enough is enough.
