Still no response - a tragic story of loss, betrayal and being ghosted by my internet provider

Everything was fine until I switched to 5G, what horrific service. I made a complaint about not having adequate internet access on my 5G for a couple weeks (1.5 months old), someone contacted me quickly and gave me advice, some made no sense but I followed the instructions, no problem. Nothing changed, I let them know, continued on this path for a couple weeks back and forth - took so long because they take minimum 4 days to reply. Still nothing was sorted. My complaint then migrates to someone else, they call, offer my money back and a sincere apology, since I would like to cancel my 5G and go back to 4G, no problem. I will need to still request for 4G on their website though. No problem, I've done this before. Tried to request, after cancelling, expecting my money would move over to the 4G and we would continue as normal... No. Sales person informs me she cannot help me with the refund, I will need to speak to the customer service that I was dealing with as she cannot see what I am talking about. No problem... Sent an email to the person I spoke to on the phone that 'gave' me my money back as a credit, no response. Sent another, no response. Person number 3 sends me an email some time later, I tell him the situation briefly in an email... Nothing. But then an email to say they have been busy for the last week with a high volume of issues and to be aware that load shedding will have an impact on my internet connection, perhaps this is the issue (side note: L/S just started, it was not happening when I originally complained), so I let him know... No response. I'm currently still waiting for a response, still waiting for my money back, I've gone the whole month without any connection as it was cancelled, I cannot get another because I've already paid Rain (debit order) and still waiting for them to arrange to collect the piece of junk 5G device for weeks now.

Their 5G is nothing but lies, they take your money and give you a version of internet that is sporadic, full of packed burst, spikes up and down dramatically, loses connection from the slightest breeze, never mind when it RAINS. I cannot search the web on one phone and play YouTube on another, it doesn't work. So this ******* about 25MB/s download isn't the case for long enough to be considered the 'AVERAGE', you barely have 500 bytes upload speed on average and that is where it gets you.

So thanks for nothing, from a loyal customer of over 2 years. Call me.
