Is this what you call customer service?

I was contacted by Cell C (my service provider of nearly 15 yrs) & offered a tablet. I arranged that I could receive 3 tablets in time for Christmas. I was approved - bank details recorded, contract read out. I received 1 of them & the sales consultant called me to say that the other 2 were on their way & would be delivered by the following week. I had also called Cell C & they confirmed the same. Two days before Christmas I called again, only to be told that the 2 other tablets were declined by credit. Furiously I got hold of Mandla Ncube from the CEO Complaints Dept & was asked to email him, which I did. In there I asked for an apology because I was told on 3 occassions I had qualified & the tablets were being delivered. I also requested they collect the 1 I had. He called me the same day to ask if he could speak to credit & I refused - I want nothing more from this company after the past 2 years' terrible service. The last straw being disappointed children on Christmas. I've now sent another 2 emails & tried to call Mandla on the cellphone he lists in his mail reply - which someone else answers. Cell C come fetch your goods. I'm so tired of your incompetence and disrespect.
