Terrible service from Telkom - extremely frustrating to deal with

Extremely Frustrating dealing with Telkom. I bought a LTE router on 8th June. Struggled for a little over a week to get it up and running but failed. Was in and out of Telkom stores. Ended up getting 3 SIM cards (On different days) but couldn’t get it to work. Even had Telkom support remotely try and fix my number (fault ***6) but it wasn’t the sim. Device likely and OBF, was told by Telkom support (call center) to return it to store I bought it. I returned device to store 19 June but told its outside 7 day OBF swap out period. Was forced to book it in for repairs (***). Paid for a device and didn’t work at all. Paid for SIM card with data which may now expire as it’s valid for 30 days and device repair is up 21 working days. In my several visits to store or calls with call Centre no one bothered to tell me I must return device within 7 days. At this point I just want to be refunded and find another provider but instead I’m left without a device and data that’s expiring
