Terrible service

I logged a service request on the 2nd February 2018, the service request was due to data loss . When Vodacom gave me an allocation of data for the current month I lost my previous data. However since I logged a service request it's been 14 days and vodacom has not updated me or acted on the service request, I called them twice and all the call center agents had to say was that it's in progress. When I put in a service request I was told the turn around time will be 7 days and today is the 14th day and vodacom still has nothing to say to me. They don't even bother calling me to give me an update. I called them twice already as if they don't know that they atleast need to update me. I'm so sick of vodacom, infect I don't see reason why I should continue being their client when they fail to attend to small matters such as this one. It's as if they don't even care.
