Telkom LTE Sim Card

Hi, last week my LTE router stopped working randomly in the morning, red lights and no connection, was going away so I said I will attend to it when im back hopefully its just down time. got back and went in on Monday morning to Telkom shop in eastgate, they said I needed a new sim card, done that and waited, Tuesday still the same thing, went back there, they gave me a simcard which was done wrong on another line, waited again. next day still no joy, called the call centre, only to figure out the consultants are working from home and cant do much. Went to Eastgate again, they are actually not helpful at all and cant assist further to my problem. today is Friday still no network, they saying there is no data loaded on my sim card, but its a month to month contract with 40Gb??? they don't know how to assist or load the data. Accounts are usually paid 1 week in advanced so its not the payment I will be cancelling this line on Saturday as I cant pay for something im not using, NO ONE AT TELKOM CAN ASSIST ME??? ITS BEEN OVER A WEEK!
