not satisfied with services

I have never had to complain about vodacom in the 18 years that I have been with them. I did the upgrade on 12 November 2018 online - see Quotation no: 1- ********** ********** Phone was delivered to me on 14 November 2018. Since the 20th of November, I've had to restart the phone every morning in order to allow all calls / sms's / emails, whatsapps , etc... to come through... I contacted vodacom on 22 and 23 November as I still had the problem, and spoke to 2 separate consultants advising them of the issue at hand. I can not go without a phone as I have applications loaded onto it that I use at my place of work. I am being told that Vodacom can only send the phone in for repairs. I need a new phone as I am not satisfied with the current phone. Also when initially doing the upgrade I requested a blue Huawei p20 lite... only much later in the conversation the consultant advised me that they only have the black one in stock... Please try to assist me as soon as possible.
