PATHETIC INTERNET AND CUSTOMER SERVICE FROM RAIN SOUTH AFRICA!!!!!!

So as per my last post, I have been experiencing extremely slow internet speeds since before lockdown started and right up until now the speeds are extremely slow. So I tried contacting rain about it and they are closed which is understandable as majority of the country is working from home. I tried reporting the fault via email to their support and nothing gets done about it. I am currently on their unlimited 4g plan which is supposed to give me speeds of up to 10mbps upload and download at all times. What I get is far worse than that. The speeds I receive is below 0.5mbps download and upload. For a company that prides itself on offering unlimited mobile lte data, I'd say that it's a complete *******. Their customer service is absolutely poor, and here I was thinking telkom was bad their pathetic customer service makes telkoms look like a bunch of angels(no offense to telkom). So finally a consultant responded to my email regarding the issue and she advised to reset the apn settings, which was a total disaster as the already slow speeds decreased drastically to 0.01mbps download. I did notify her that the speeds went worse than before but she constantly advises to change apn settings, she then escalated it to the networks department and they advised to change an settings again( do you honestly believe that changing an settings resolves every single problem that a customer experiences? Do you not have a plan B?), so I offered a few suggestions like changing the frequency that I'm on or moving me to a different tower, and guess they got no response. Like seriously guys, does your clients have to give you advice on how to help them? Its been over 3 weeks since that email requesting assistance and no response from them since. So I decided to post here and finally they do respond promising me that one of their team leaders by the name of marvin would contact me, and its been quite a few days now since that response but no team leader by the name of marvin has contacted me, honestly at this point I feel that I'd have a better chance of getting God almighty to call me than somebody from your company. This is unacceptable stop ripping people off and give them what they pay for.!!!!
