Disgusting

I went into MTN Sandton City on Sunday 15 September 2019. My cellphone had been ****** & I needed a sim swap. I signed all documents, paid the fee & was told it would take 2-24 hours. By Monday 16 September 2019 I was told by customer services that the store had not completed my request. I called the store to query & was told they will submit it. I asked if I needed to go in & was told no. Its after 8pm the store is closed, my number is not active & customer services says the store has still not submitted anything.. Getting a simple sim swap from MTN has now become more complex & traumatising than actually being ****** & having my phone ******!! P.S I am nearly 9 months pregnant & need access to my phone for emergencies & MTN does not seem to be bothered at all. Yet I will still be billed without any delay..
