Standard bank mobile

A week ago I took out a Standard bank data contract. Upon receiving my modem and sim card I realized that it was not working. After a lengthy conversation with the call center we managed to get it working. On Saturday my wifi went out again and I was only able to get it restored on Monday at 6pm as their call center is open on Saturday afternoons nor Sundays. Today my wifi goes off again and the call center is closed. It's costing me more money now buying data on the days that they can't provide the service that they promised to. I don't advise any to get this product as you will only have issues with it, issues that can't be dealt with after hours😢
