BAD BAD BAD Service

I needed a data provider and tried RAIN ONE HOME at R649 per month. You would think for this amount per month, you would get some sort of support services so that I can actually use their product. My issue is that I can't send out emails and my hosting service provider thinks it is because Rain has blocking certain ports for "security" reasons. I have attempted their pathetic online AI bot, their WhatsApp AI number, I have now called their call center three times and keep getting cut off, it sounds like they are based in India. I have also emailed two different email addresses multiple times. Where is the customer service. Better to retain clients and get new clients threw word of mouth... Customers are just numbers to RAIN. Oh well, they have just received another customer who will never use Rain again and I will certainly warn all my friends and acquaintances about this BAD BAD BAD Service!
