WhatsApp ticket issues

As a Vodacom customer for years I am very disappointed and quite frankly disgusted at the lack of customer satisfaction that Vodacom has displayed the past week. Vodacom has been experiencing issue with their WhatsApp tickets, which from what I have been old effects someone of their customers oppose to all. This issue has been happening since last Wednesday. My disappointment comes with the fact that instead of working to resolve this issue Vodacom says that this matter could only be assessed after the weekend as their technically team does not work weekends. This I understand however given the situation should Vodacom have in place measures that ensure issues resolved regardless the day of the week? Upon calling into the customer care line just after 2pm on Monday I am now told that there is still no resolution or any feedback expect that they have escalated the matter and that it is been dealt with.. Vodacom did not even send out any form of communication to its customers informing them of such issues to begin with. This is really disappointing and truly brand destroying as I for one will be rethinking my service provider when it comes to my contract upgrade.
