Customer Service

I have a problem with customer Service. Not helpful at all. I contacted the customer service centre. the person I spoke to was not helpful at all.my query was how was my number ported to MTN with out my permission. The lady I spoke to just kept saying this not an Cell c Number, I could not get a word in edge ways. I have proof on my phone that I was paying for Airtime and Data. In the mean time because my number was ported to MTN my bank account was compromised, if that consultant worked for me I would fire her on the spot. If no one comes back to me and explain how this can happen I will move to another Service Provider. Total ******* service I went to the Cell C shop in Alberton to find out why I had no Service, thats how we found out it had been ported to MTN. No idea how Cell c can do this with out my permission. I won't speak to Customer Service ever again, maybe they should take a step back and listen to what the customers query is, without jumping in feet first
