Rain - Bad Customer support - Bad Service

I am so frustrated right now with Rain it has been 3 months i did a 5G upgrade on one of my packages and the sales consultant did this for me over the phone because they cant upgrade you from 19 hours unlimited to 5G they have to first upgrade you to 4G Unlimited then 5G, so i have received the 5G Router and sim it was activated, month end August i get billed for 4G and 5G, i query the account i get a short credit on my next bill then invoice me again for the same package with no data used no sim card because i am now using the 5G they offered to rectify and credit me because its the second time got *** so since then no credit no getting back to me via email because they say when they call me the call is not going through so all this times i am the client calling and waiting on the line for 10 to 15 minutes every time i query this and remember their line as soon as it rings you are being charged not when they answer. then i managed to login and cancel the 4G sim card i didnt use for 2 months and i got billed for it again now for December my bill is even higher there is no credit on my account or refund for last 2 months of having this 4G Unlimited package that was upgraded to 5G, i could have just cancelled the 19 hours unlimited and ordered new 5G it would have been far better i am so angry i gave them an alternative number when i logged a call today so that they can call me and still even not no response on email or call new ticket number *** , to think that the internet doesnt work when its raining and we are still supporting them they better get back to even on twitter they dont respond.
