TELKOM DISGUSTING SERVICE

Good morning, I am currently VERY VERY VERY VERY VERY frustrated with Telkom!!!!!!! I recently got a new contract with telkom which was the LTE-A 40GB (20GB & 20GB)(Which i thought was the contract that was supp**** to me) Unfortunately the deal was not working for us as the Data runs out too quickly. I then decided to go with ADSL 10mbps uncapped and was prepared to pay a cancellation fee of +/- R 2,800.00 but the ADSL installation technician told me that i was too far from exchange and will only be able to get 4mbps to which i then cancelled my order. NOW THIS IS WHERE MY FRUSTRATION COMES IN... I SAW TELKOM HAS A NEW DEAL FOR 400GB (200GB & 200GB) ON LTE-A. I PHONED THIS MORNING HOPING TO MIGRATE MY CONTRACT (AS IT IS A LITTLE OVER 3 MONTHS OLD) TO THE 400GB DEAL. THE SALES PERSON TOLD ME THAT I CAN NOT MIGRATE TO THIS CONTRACT, AND I AM NOT ON LTE-A BUT ONLY LTE, ALL I WANT IS MORE DATA WITHOUT ALL THE DAMN NONSENSE, IVE GOT THE ROUTER, IVE GOT THE DAMN SIM CARD! WHY DOES TELKOM MAKE IT SO DAMN HARD FOR ME TO SPEND MORE MONEY WITH THEM?????????? I AM FED UP WITH THE ABSOLUTELY DISGUSTING SERVICE AND OPTIONS THAT IS CURRENTLY BEING OFFERED TO ME. SURELY SOME SORT OF SOLUTION IS THERE FOR ME TO GET THE 400GB DEAL. PLEASE GET IN CONTACT WITH ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!
