Unbelievable BAD Service

I started using the unlimited Rain 4G data sim card since April 26 2021, I sent the service providers technicians a message on the 28.04.2021 that i have a very poor signal and i am struggling to connect with my work systems. I also mentioned that i checked the base stations near by which are 4 in total and all of them are less the a KM away form my house. I live in a residential area which has no high building no any building structure that will obstruct my connection. I have not received a response nor a call from them to assist me with my endless connectivity issues. All they do is communicate about about my month to month invoices. I am paying for unlimited data every month since April but i am not getting what i am paying for. I also think that they are unprofessional, they have not contacted me in any form regarding my call that i logged with their technicians in April and now we are in July. I feel that they are violating consumers, we are not receiving what we are paying for which is against the consumers rights.
