Telkom Mobile LTE poor connection

LTE connection fine till 2 weeks ago. Device tested at a Telkom store, and confirmed to be functioning 100%. After 3 calls to report the problem in the past 2 weeks. It seems that nothing was done to resolve the poor net work 3G and LTE connections. No one contacted me to say something is being done. Every time I phone, a new call is logged, I get no feedback on a reference number given. The Telkom LTE network in the Stellenridge area in Bellville Cape Town is not working. I have to pay my contract fees, but I have no Internet. I am not receiving the service I am paying for. I am not sure why anyone is still supporting Telkom. This is the reason why they are losing about 100 000 customers a year. Telkom please fix the problem and boost you mobile network in the Stellenridge area. It should not have to come to a complaint before you fix it or listen.
