Network Signal Driving Me Mad!

I've been with Vodacom for many years and it's becoming increasingly difficult to get a network signal. Sometimes for a week or two I have no signal and I am so frustrated. I'm in Bellville, Cape Town and my family on Cell C network and MTN network have no issues while I can't use my phone because despite having 100/100 fibre WiFi I have no connection. I'm sorry I renewed my contract, it's time for a change this is ridiculous. You can't report it unless you call in and then you are talked through all the same checks I've already tried... It's not me Vodacom, it's YOUR NETWORK! Sort it out already.
