BAD MOBILE INTERNET

Still sitting with the same mobile problem for 4 weeks. At night I lose my full bar 4g + signal and end up with a 2 bar normal 4g signal. Please MTN explain this and do not tell me it is due to loadshedding as that is a lot of baloney. This affects my online gaming and costs me. I have complained about this 3 times already and you have not even bothered responding. Is this how you treat loyal customers of more than 15 years. YOU ARE LOSING IT MTN. I THOUGHT YOU WERE SUPPOSED TO BE THE TOP NETWORK AND ESPECIALLY FOR GAMING. FIX IT AND THE OTHER ISSUES YOU HAVE
