Vodacom network sucks

Ever since I changed my number to contract, at least once a month vodacom network seems to disappear or become extremely slow. Such that it can take about 10min to open a page or simply time out, for at least 20min where I cannot make phone calls, browse internet, send sms, etc. I cannot even dial vodacom customer care. I have complained about this in the past and the vodacom customer service personnel told me there was nothing wrong with my network/line. I asked for a reference number because I knew this will happen again, but was not given one. Case in point today 13/02/19 from around 12pm. I even restarted my phone twice just to make sure This is annoying, and I hope vodacom can fix it????

For reference I'm based in Stellenbosch, there's sufficient signal from here. Just that vodacom seems to like annoy me personally, i think.
