Breach of contract

Good day.

I would just like to inform everyone about the way I have been **** to. For the past 7 months I have been complaining about network related issues. I was advised by there network department that the contract will be cancelled and I will be refunded as of the date of first complaint. A month on and i am still in the same predicament as I was 7 months ago. Having to phone them at least 10 time a day now i cant as they have blocked my number. The only means of communication is via email that i send every hour on the hour with no luck.
