Absolutely appalling service!

I have just received a threatening email regarding my arrears with CellC. It seems as if my complaint is not taken seriously at all.

My phone was ****** on the early hours of the 17/06/2017, I blocked it and submitted a claim at their Newpark store in Kimberley on the 20/06/2017. Despite the fact that I had to do the following up, I only received a response months later on which CSurance (their insurance provider) advised they could not process my claim, because I had not used any of my services since December 2016, even after more than one CellC consultants confirmed that I last used my services just after 12pm on the 17/06/2017. I sent them my itemised bills on the 07/08/2017 as per their request, and guess what? We are a couple of weeks into 2018 and not only do I not have a phone, I have not even received any correspondence whatsoever!

So before you take any legal action against me for not paying my bills - for a service that I don't use to add on. I am not paying for a service I haven't received in months!
