Very Bad customer service

So today I decided to go to Vodacom lakeside mall because I have a problem with my router the download speed and upload speed has been bad on my Alcatel router for a while now. But I was sent to one of the baddest consultant ever by the name of Paulina she didn’t even try to assist me only thing she kept saying was that my account is in arrears and there is nothing she can do about that instead of advising me on what steps I should take to fix the problem I had or how she can be able to assist me That lady is very rude she has no customer service skills of any sort,only reason am still using Voda it’s because of my contract but once it comes to an end am cutting all ties with them period.!!!
