Nightmare to deal with Telkom mobile

I took up a new contract with telkom . then i later released that i am unable to surf the net with the tablet, so i phoned telkom to ask what the issue was? then i was told it is because the contract is telkom data and not all network data. so i can only be able to use it it i have telkom network and not if i am roaming like i do. so i had no choice but to return it as i am unable to use it because there is no telkom network coverage in my area. so i took it back to the store on the 05th of Jan 2019 to cancel the contract, and i was told it is cancelled.that was still withing the 14 day period of me taking up the contract. come 22nd of Jan i got debited a huge bill and when i inquired i was told i have 2 contracts. so i told them that according to me the second one was cancelled. unfortunately that was not the case, was told to go back to the telkom shop in pretoria to follow up with the cancellation. and i told them that will not be possible as i work in Standerton, and it is more than 250km per single trip to go there. so i was advised to log a case on their website then they will try assist with the cancellation. today is the 04th of April and the contract is still not cancelled, i don't have the tablet but i am still paying for it. Every time i call i get told they still working on it. and a couple of days i got an email from telkom saying my case is resolved, no additional information was provided. only that i need to contact them on their call centre number for any related queries. this begs another question, if they are able to send me an email to say my case is closed, why cant they elaborate on the email instead of me having to call them and hold for more than an hour waiting to ask what was the resolution. but i had no choice but to call them. then i was told that my case is not resolved, the reason i got an email was that their retention department was working on my query. so they are now waiting for feedback from the store as to where is the device. they have send an email to the store on the 29th of march to request that information. but they still waiting for feedback from the store. that is a week later, no feedback from the store in Wonderboom, Pretoria. so i asked what next if the store doesn't reply, and i was told that they will reply, but not sure after how long. the lady even advised me that i should go back to the store to ask them to reply to the email so that the matter can be resolved. so i explained to her again the distance that i have to drive. so she tried getting the stores contact details, which are obviously blocked and redirects to the call center. and worse again i got their invoice today again, which still shows 2 contracts. what more can i do? the consultant at the direct sales even send an email to the store to contact me but still nothing. so i wonder if the device is there or they lost it, but in any case that is not my fault as i left it there at the store.
