Disappointing customer service, worst internet speed!

So much has changed in a year. Last year July I gave Rain a 5 star rating based on the great service received in getting me signed up and connected. A year later and I am so frustrated and disappointed with the poor customer service. I have sent so many emails over the past few months, with speed tests to back up how slow my internet speed is. I’ve tried repositioning my router and everything else suggested. Just experiencing constant lagging and buffering and disconnected work meetings. And there’s no response to my emails. I understand that their network is clearly strained due to lots of new customers over the lockdown period. However the company should not take on new customers if they don’t have the infrastructure to support them. I am now looking for a new service provider because I can’t continue like this with ridiculously slow internet and non existent customer service!
