I will not be upgrading with this company

I requested a sim swop, as I needed a normal sim after having a nano sim.<br> <br> At no time during this whole process, was I ever informed that I will forfeit my current airtime and data bundle. When I finally asked about this, I was just informed that I will need to set up airtime and a data bundle.However, the call centre member could not inform me how I should do this. I have a everyday contract, and not prepaid or topup, so I cannot simply load airtime. I was also not informed if my data will be back to normal at the start of December.<br> <br> My contract runs out in December, and I will not be renewing it, as I so unhappy with the level of service given by this company.<br>
