Complaint for purchasing services that cannot be delivered by Telkom

We are in holiday and bought mobile data to use on a router to watch movies. Before we bought the data we checked that the sim worked in the device. After we had purchased the data and kept being dropped we contacted Telkom only to be told that there was no coverage where we are but that the data couldn’t be refunded as it would work elsewhere. We explained that we don’t need it else where as we have uncapped data at home and therefore wouldn’t need to use the 200gigs elsewhere and that was the purpose for mobile data. When we bought the data it only offered 2 options LTE and LIT and these were not explained at the time of purchase. We spoke to Lesego and asked her to log the refund and she was then instructed by her manager Andy Maboshego to not log a request for a refund as the data.
