Telkom Customer Services Sucks!!!

I have app**** online for an Uncapped Deal...The next day one of the Telkom online agents called me and processed my application which was successful, The couriered me the LTE router with a simcard but the simcard is faulty and I cannot use the wifi benefits...I have already received my first account of R1290 but haven't use their service due to a faulty simcard that they have sent me..When I phone customer care i am holding for 40-50 minutes and still they cannot assist me...On the 11th of June 2020 I phoned their customer care and spoke to Thabisile who tried to assist but couldn't because she had to refer my problem to their Technical department who was supposed to phone me back within 72hours with reference number ***0...THEY NEVER CALLED ME BAC**** I phoned again this morning and waited 40 minutes again spoke to Katlego and she informed that my case was only assigned to an Technical agent yesterday now how is that for Urgency and Customer Service!!! To top it all up I now have to wait 24hours again...I REGRET SIGNING UP WITH TELKOM!!! TAKE YOUR DAMN ROUTER BACK !!! I AM GOING TO REVERSE YOUR DEBIT ORDER BECAUSE I HAVE NOT BENEFITED ANYTHING...My name is Edward Miners, My account nr is *** and the simcard nr ***...I Demand a new simcard to be couriered to me after you have done the simswop because I am staying more than 300 kilometers from your Telkom shops
