African can mobile is ******!!!!

I took out a cellphone contract with African mobile almost 2 years ago. I was paying for insurance on the phone and the data and airtime which I never received in the time of me having the phone. When my phone got ****** and I eventually bought a new phone and got hold of them via WhatsApp as nobody ever responded via email there was never a response. I kept getting messages of "this conversation is closed" so I stopped making payments as I did have insurance on the phone and they were not willing to replace the phone. Never mind the data and airtime I had never received. Now they harassing me every other day and when I said to them let's go to court about this. Summons me because you were the one that broke contract rules not me. I would never advise anyone to buy or contract themselves with a phone from this business as there are many who are also paying for phones they haven't even received. African mobile are a bunch of ******. Never commit yourself with them no matter how desperate you may be
