Ongoing query for over 8 months

I signed up with Rain 5g early last year due to the need to work from home. The main reason I chose Rain was the packages offered on the marketing material. I singed up for the standard package after speaking to Ebrahim in sales who confirmed that the package was unthrottled, uncapped and unshaped and there was no fair use policy. I started experiencing speed issues in June last year. After a month of trying to resolve the issue I contacted the support team. The issue has never been resolved ever since. I have tried to impress the support team with the urgency of the issue and they seem not to give this issue the seriousness it requires. There have been over 6 technicians who have visited my premise and done tests and optimizations and came to the same conclusion. The issue is not with the device but with the account. The latest who came on Friday 12 March 2021. Using the same device but with his sim card, he found the speeds were fine, however using his device with my sim card the speeds were at a maximum of 4Mbps. This has also been confirmed by the previous technician sent I have done tests and sent though evidence of the same. One of your agents advised (on Thursday)that if I want I can go ahead and cancel as there is nothing that can be done. He did promise to get back to me by end of business Friday 12 March 2021 after the technician's site visit which he has not despite me sending him an email to follow up on the matter. The support team keeps taking me around in circles, not realizing that this is costing me time and money as I cannot meet my deadlines, I cannot attend some meetings and I at times have to make other arrangements to stay connected due to the poor speeds. Some of my concerns are: 1) When I signed up, I was promised speeds of 30Mbps, I am getting less than a quarter of the promised speeds, yet this is the main reason I signed up 2) Is my business not that important to Rain that the issue has dragged on for close to 3 quarters of a year with no actual resolution? 3) Every time I am contacted by an agent I have to go through the same story I have explained before. 4) The attitude by the latest agent is quite disturbing.
