LTE Signal and Phone Line

My problem, I have a fixed line look a like and after working for a day it says account suspended and now it just keeps saying limited service. I took out the sim and battery and then put it back it doesnt help. So from around 18th September I had no service.<br> <br> Also I took a package with LTE internet, 5Gb and 5GB after midnight but the signal is very poor and on the telkom website it says I should get LTE signal. You'll sent a technician and he agreed the signal is very poor. What are you'll going to do? He also said we should have an all network sim but we only have a telkom sim.<br> <br> Get back to me asap on these it is ridiculous how long you'll take to sort this out. This is the second report I am writing on the issue. Call me and let me know what is going on!
