Poor service and product delivery

So I opened a contract at MTN Northgate....I was approved ,I was told they did not have stock of the Samsung A32 that wanted with the watch deal.... I was told there ONLY one watch available as I requested two with two phones.....they said they had to order the two phones from another store with no choice of colour....no problem I said... Go back the next day to collect two phones and one watch ...the phones were there plus one watch .. only to be told those phones had now been pre booked for another order they cannot be released but they will rectify the issue.....next day I go back Same problem!!!! I then ask if the A53 is available with the watches ...yes they have stock of the phones but still only one watch .....ok let's do it ....I get given the two phones and watch but get told I cannot use the phones until the two Sims are activated which would be on the following Monday.....today is Wednesday ....Sims still not useable....I cannot use any other network in my new phones as I will lose my warranty.....Sims still not available as there's an issue with the two phones IMIE numbers now for whatever reason.....I'm sitting with two new phones I cannot use....*** ?!!!!.....I'm told new Sims cannot be given due to the IMIE issue ........I enquired about an option for a better watch...was told I'd have to apply for a new phone!!!....what's the deal....new phone I cannot use and also told o cannot get my original request for two phones and two watches...MTN please resolve this I'm not happy
