VERY POOR CUSTOMER Service

I spent the past 2 days trying to solve a issue whereby i "UPGRADED" My service and spoke to x2 Rain agents after waiting for hours in ques for both agents to leave the chats without helping me, they were very rude and did not seem competent at their job, i went as far as to help them understand the meaning of the type of service issues im experiencing so they can understand how to better help and all i was informed was to keep turning on and off aeroplane mode. I had no issues in terms of line speed before this upgrade to their 24/7 service. Not to only mention that i have a 2nd sim line with you guys and that one works just fine without the unlimited option, we are subjected to under 800kbps this is standard Edge hardly 3G connectivity. This is not what im paying for. I know what i should be getting. Please address your rate limit service accordingly. Time is money and i am using this resource to work. Please have this addressed ASAP. Thanks for your support in advance.
