Unacceptable LTE speed!!

For the last month I have been receiving speeds less than 1Mbps. After calling the Telkom "Service" desk, I was told the problem would be fixed within 24 hours. They also don't give out reference numbers and I assume this is because they don't want customers being able to follow up. It has been almost a week and not only has the problem not been fixed, it has gotten worse! Now both of my LTE lines keep getting no signal every 5 to 7 minutes, on 2 separate routers and in different locations. Telkoms service is ridiculous. This company should not be allowed to sell products to the public due to their lack of service and unwillingness to resolve their technical issues. Get your S**T together Telkom and do something about your damn LTE speeds. Telkom should add a clause in their contracts stating that should any customer try to take another contract with them, the customer should be shot in the head for being so stupid. Telkom, you are a disgrace to ISPs.
