Poor service

I went to the Vodacom store on the 3rd of June 2019, a consultant helped me to order a Lenovo Ideapad for me, he was not certain when the laptop will arrive and I left my contact details with him. I contacted your upgrade department on the same day, they helped me to order a Mecer Xpression as it was the only one available. The person that helped me said that I will receive the item in 4 days and never read the terms and conditions to me. On Thursday last week the consultant phoned me and informed me that he received the laptop, whereby I declined the offer even though he also said that he will still give it to me on the old price before the increase. To date, I did not receive any call from your offices, nor to confirm, and also not getting professional help with my upgrade Another person then became rude when I told her regarding the 4 days that was given to me, and said it was 3 – 7 working days to receive the upgrade. I’m just getting answers the whole time that the confirmation department need to phone me. I was also informed during the weekend that they’re not at work and that I must phone again on Monday I phoned on Monday and was given the answer again that they cannot put me through as they need to phone me. Today is the 7th working day, and did not hear from your department yet. I want this resolved
