POOR SERVICE after ********** sim swap

My MTN sim card was **********ly swapped without my consent on the 27/09/2017 and I subsequently could not use my number. I visited the MTN Rosebank Mall branch in Johannesburg where the staff members helping me were disinterested in my complaint. They assisted me with reversal of the sim swap, however after 48 hour it seemed the reversal had failed and I still could not use my phone. Much to my frustration, I contacted the branch again and the ladies (one of them is Lindiwe) at the store were rude and dismissive. They deferred my complaint to the call centre and told me they were busy with customers (as if I am not a customer). I requested to speak to the manager and I was informed that the manager is not around. They took my details and promised to call me back. Up until this hour I have still received no correspondence from them or the store. These ladies had no respect for me as a client and showed no professionalism. Kept on referring to me as "my dear." This store displayed poor service and obstructive behaviour towards acknowledging my complaint. I was appalled by the service at this store and even until this hour my phone is still not working!
