No signal

Rain has been working well since I had purchased it and before I did, I checked which areas were covered. Since the lockdown has commenced, rain has not been the greatest at all... most of the day I suffer and have to buy data due to “no service” which means I don’t have any signal at all... I reboot my phone a lot of time but still doesn’t help. I am actually paying for my contract for sweat nothing... I struggle so much . I want out of this contract period . I am unable to work and they had promised us good download speed.
