Accused of being a *****

I renewed my contract with Vodacom in January - I had an iphone 6, 7, 8, 10 and now 12 with them. Before that i had numerous other type phones too. I moved to them after being with MTN for many years. When I renewed in January everything went smoothly except the service sucked at the store and continue to suck. So much so that after trying since January at the same time as when I renewed the cellphone I tried to get a wifi router contract for R159 per month. Today when I got called to arrange for delivery all of a sudden I am **********. This after I successfully passed your verifications last week. I signed a contract for 2 years on my cellphone costing me almost R2500 per month but you tell me I am ********** when trying to do a R159 contract? They are not phoning me or even trying to discuss. I get told on messenger by one of their messengers that I am ********** and they are sticking to their decision. Don’t you think I am entitled to know the reason? My son who is 10 years old was phoned by them today on his Cell C phone number - a contract also on my name and they had a discussion with him? Why? He had no clue who or what it was about. Since when does a company like Vodacom phone a 10-year old child? Disgraceful!!! I am still expecting someone to phone me to explain this. I am in a financial position at work and deal with verifications and FICA on a daily basis for the last 20 years. I will take this matter further
