Bad Client Service

I lost my phone on the 27th of February and have been trying to blacklist the phone since without any help. Consultant in a cell C store that was in Jubilee mall have bad client service. They don't acknowledge the client when they walk into the store, they busy on their phones. They couldn't assist me and that delayed the process. The store is currently closed and I think that's the reason they didn't care. This behaviour needs to corrected as we spending our money to keep cell C in business. They need to take their consultants to customer care courses. This is really a horrible service I have ever received so far.
