Request of Basic but urgent Info on a MultiConnect/DataShare Contract is a Pain to Obtain

I have a MultConnect/Datashare plan with 1 Primary plus 5 linked Sims. I have already given some suggestions and have a reference for an Urgent Request for Usage information so that I can audit/verify consumption for April 2018. However as my usage is depleting faster than expected, I today called Cell C twice to get some basic information on the respective SIMs. I am very surprised, that both Technical and Contracts cannot give me some very simple information that will enable me to take action before my data depletes. All I wanted to know was: 1. What was the date/time when the Linked MSISDN's were last used. 2. Possibility to temporary deactivate one of the Linked sims (based on response to #1 above)

CSR's could not help! Finally. its unfair to ask me to rate a CSR, when they are generally helpful and have tried to resolve a query but they do not have the tools/systems to do so.
