Maurice D Bad Service

There is no room above for a minus rateing! We subscribed with Rain for a 4G 24/7 service but since its inception last week, although the signal is present, there is no internet between 6.00pm and late! I can only assune they have erred and all it would need is to change the settings. They have now received three messages from me all of which gave me a referencve and assurance that an agent would cintact m,e. They did not and their "Call Centre" is closed and I cannot find a telephone contact. If they are interested one of the weference numbers is ***.
