Bad Service

For some reason, service delivery is too much work for them. They are happy to receive our money without fulfilling their end of the deal. I am a user of one of their smart prepaid meters and after transferring money into their account on a Friday between 4 and 5pm I was given only about a quarter of the units I had paid for. Upon calling the person responsible for this service on ********** , I was told I will have to wait for Monday as there was nothing he could do about it. Should their clients suffer for their malfunctioning systems? It is their responsibility to make sure their systems are working properly to avoid receiving calls after hours otherwise we forget about their smart prepaid meters and return to the conventional one. I do not mind complying with their requirements but I request they take their clients serious as they seek the convenience they get from their services in exchange for their hard earned money. Please improve.
