Atrocious Service from Vodacom

Over the last month , vodacom has shown such incompetence & unprofessional client service . I app**** online on the 17th JUNE & it was approved in less than 10min. Phone was delivered the very next day. I cancelled it on the 18th June, then went into the vodacom store on the 19th to confirm cancellation. With 90% of my calls dropped and being on hold for over 15 min, over R400 debited for a phone they are not collecting that's sitting in a box. they eventually picked up the phone on 16th JULY. Today, 22nd JULY, i tried calling them (as they instructed me to , to confirm cancellation) the first call was dropped, second call i was on hold for 6 min, then i call back for the 3rd time and I am told THAT : I've been blocked and my number has been flagged as a risk, because ive called too many times ?I HAVE CALLED TOO MANT TIME?? ??I AM SICK OF THIS ****?!!! BECAUSE OF THEIR INCOMPETENCE!!! I AM SICK OF THE POOR CUSTOMER SERVICE , RUDE AGENTS , PATHETIC TURN AROUND TIME and overall communication of this company . I WANT ANSWERS !!!
