No assistance or feedback

After receiving my data sim card within 3 days from ordering date, I was very impressed and excited to use my 4G 19 hour uncapped data simcard just to get disappointed a few hours thereafter. I inserted the simcard in my LTE router. It didn't had much signal in the house but moving it outside didn't made a difference. I could barely read something on the internet without having the page loading when turning the page. I inserted the sim card in a 4G router as well as my phone but no internet. So just the day after receiving my sim card I emailed rain for assistance and received a automated response stating that they will reply within 24-48 hours. After 2 days still struggeling and trying to use the internet I emailed again after not receiving any response from my first email. After a week of me trying to complete my studies and my mother trying to work to receive some income for this lockdown period I decided to cancel rain as to date (more than a month later) I haven't received any feedback from them and as their call centre was closed and email was the only contact I could have them but haven't received any assistance. I had to take out a contract from another data provider. With the cherry on the cake I had to pay 2 accounts at the end of April as rain deducted money from my account (without me using data for that month) and I had to pay the other data provider. I am very disappointed in rain's assistance and would discourage anyone who wants to take out a contract with rain. How can you sell a product like this and not be available for assistance?
