Bad customer experience/service

I ordered the rain simcard online and paid immediately...this was on the 28th February 2021. I waited the whole week to receive my simcard from REM courier company...this was my first issue. My biggest issue now, is that I'm stuck with the simcard I cannot use, when I insert it on my device...it says there's no network. Their customer service is unreachable, since they only work from Monday to Friday (08:00 - 17:00). I have paid R479 for nothing...I cancelled my contract with another service provider thinking that rain was better. Joining rain was the biggest mistake...I really regret this decision. The sooner I cancel with them, the better. Please stay away...other service providers are better...at least you can reach them after hours and on Saturday and Sunday. Their customer experience is the worst.
