Terrible Wi-Fi connection

My moms Wi-Fi has been out since beginning of December and the unfortunate part is she can’t find assistance cause apparently when it was rapidly installed she was told an email will b sent but she hasn’t received anything and now the Wi-Fi has been down she She is in Jabulani flats in Soweto. A week before hers was down most of her neighbours had Wi-Fi problems a representative did rounds but because my mom Wi-Fi was fine ofcause the passed little did she know she was nxt she should have asked

She is an elderly person the consultant that dealt with her had to do a complete job and leave all the necessary contact details she would need

At this point I need assistance cancelling so we find a better supplier
