Vodacom Online Contract Sales bad service

I'm so disappointed with the service I got from Vodacom online sales, I app**** for a contract with Lungani on 15 September which was approved, and I asked that my prepaid number be used for the contract number instead of getting a new number, I was then told I can go to any Vodacom store, where it can be done. Received my phone 27 Sept 2018 and went to Vodacom shop where consultant told me it cannot be done, I had to return the order, after numerous call eventual the phone was collected on 3 October, and Lungani called to update the order, however now the price was increased, I insisted on talking to the manager, and was told the manager didn't want to speak to me, but he will get a higher lever manager to call,.....after numerous calls for a few days again I spoke to a Londi on 15 Oct who promised to get someone to call me back to sort this out..... up till today, no returned call. I have been a Vodacom customer for over 10 years, and this is the treatment I get??
