Telkom "NO" LTE - DISSAPOINTMENT

I bought one of your 5GB My-Fi devices on the 11th March 2016, thinking that I can move from Vodacom to a "better" & more "affordable' service provider. Since then I have not been able to use this device. I live in Linmeyer, where I was told has such GOOD coverage for LTE. I logged a fault on the 1st April 2016, at your Telkom Branch, The Glen, ***. I never heard anything until Tuesday, the 26th April 2016? After I am told that it can take anytime for a technician to pick up the job. Eventually Kabelo came out on the 26th & Advised that the reception is really bad & They will get back to me. Until today, I have had no call & I have been calling in, there is no call references from your consultants and I think this is very very unprofessional!! I was advised on the 18th April that there is a 24 hour call back period. A debit order of R198 went through on the 26/04 &I returned my debit order on the 28/04. However, I have now made the payment back to you in order to not have any other issues - Today,the 3/5/16& I now have a ***, which I have been advised by your accounts department, that it should be updated within 24-72 working hours from the technician going out. All I would like is to cancel the contract&Go with a service provider, where I can actually GET SERVICE that they advertise. Can you please get back to me& provide me with some feedback & A return of ALL of my money paid for your so called "service". I will rather pay more money and get my service, as now I am spending more money EVERY month on buying PHONE data, because my "WIFI" does not work!!!!!!!!!!!!!!!
