Rain 5G premium

Rain was very quick to take my money for a 5G subscription service but refused to provide me with a refund. At the time of application, my area did not fall under the 5G coverage area but the sales person promised me that if you turn the CPE in a certain direction, you'll get 5G service and that I will be eligible for a full refund within 30 days if I am not satisfied. After mounting the CPE up high on the roof, I was able to get a 5G signal intermittently but with a weak signal quality. On several occasions, it'll fall back on 4G. 3 different technicians came but were unable to improve the signal. I therefore decided to cancel the service and was expecting my refund. However, I was then told that the refund policy only applies for the first 7 days! This is not at all what I was promised. I would like everyone to be aware that the refund policy is only for 7 days. I'd also like to point out that it took Rain more than 7 days to send technicians which again shows how inappropriate that timeline is.
