Poor Sevice from Cell C

Shocked at the attitude and bad service received from Cell C in Hillcrest Durban.I called to port my number from another provider,supp**** all the documentation asked for and paid them for the service.The sim swop did not happen.I now sit with a Cell C sim with a different number that has caused me a lot of inconvenience.My grandaughter is diabetic and has a warning device app on her phone that now does not work..The attitude I received was that it was not Cell C's fault and that someone else must have caused this.How can a company take your money and then when there is a problem simply turn a blind eye.Shoching and very poor service.Cell C will not see me again.!!!!!
