Telkom does not value their customers

Telkom is one of the worst network provider I have dealt with. In 3 years I have had to do 3 sim swaps because their sim card just dies/ cannot logon to the network anymore and the worst part is I have to drive to the store to do a sim swap. This time I lost my bundles as I was at my village and there is no telkom store. My sim just couldn't connect to the network anymore and I lost my bundles and on top of that I had to buy a sim and recharge it while I had bundles. The telkom store in Menlyn could not help me with the expired minutes/SMS and bundles that expired while I couldn't log on to the network, they promised to call me and never did. Their twitter support team flatly refused to refund me for the lost bundles and airtime I lost during the time I couldn't use their service due to their fault. I have been buying the 28G free me budle religiously but I have to reconsider as I don't feel that Telkom does not value me as their customer
