Telkom LTE

On the 23rd of November 2018 I requested an upgrade on my LTE to uncapped for R899,00 per month. A lady from Sales called me and we discussed my options and I mentioned to her that I am opening up a business in Malelane, Mpumalanga and would need the service for the business. As I was already an LTE customer and at the time residing in Centurion, Gauteng we went ahead with the upgrade. Upon our arrival in Malelane, we found that there was no LTE service available in the whole area. I called the 081 number and spoke to a lady in the customer service department who checked the services and she confirmed that Telkom has no LTE service, she also mentioned that the intitial Sales lady was supposed to have checked this before we continued the upgrade. She agreed that the service would need to be cancelled as Telkom cannot provide the service, she also mentioned that there would be no penalties, as the fault was on the initial Sales representative's side. She did however mention that the Technical department would be in contact with me to offer some alternatives that Telkom can provide. This conversation happened on the 3rd of December 2018 and still no one has called or advised me. I have been to a Telkom store but they cannot assist me as they cannot process cancellations or do anything for me on their side, they keep referring me to the call centre. I have tried calling the 081 number again but it seems not to work in Malelane, although I sms'ed the number as well, as it is stated that they will then come in contact with me as well, but yet again ... nothing. I have been a loyal customer but after this episode, I might as well just stay away for good. Nothing can be resolved if they do not come back to me or offer me a solution to my problem, and to make matters worse, they sent me an invoice today for a service I cannot use.
