Poor LTE network

I have been complaining about my LTE internet since the 19th October 2018.I took out the LTE package 14/10/2018 where I had speeds of 12mbps MAX that went down to 5-7mbps then 1-2mbps. After I complained, a week later my speeds were up to 22mbps MAX which I am satisfied with however, that didn't even last a week. For the last 2 weeks I am getting 2mbps MAX on download. I have been patient, I have been understanding, I have been nice enough... I have been a loyal Cell C customer for 8 years and this LTE resulted in a deal breaker. I moved from Telkom ADSL(I have my reasons why) to your LTE and this is much worse than Telkom's ADSL. The internet is so unreliable, slow, cannot multi task.Sometimes when I open a web page it disconnects right away then I have to refresh the page to eventually load it. It is so frustrating. I can understand that I can't get 20mbps all the time 24 hours a day 7 days a week all year long. I understand the service is limited when it rains or when there is wind but there are days without weather and the service stays the same which means you guys are talking nonsense. I would like to cancel this service as it clearly is not working in my area.
