Horrible upgrade horrible service mtn

I have been trying to get a new phone since december and due to covid going to atires are stressful. Not forgetting the lack of help amd info you receive at stores like you bothering them. The store at chatsworth centre told me i could upgrade one phone. The store at the pick and pay told me i can upgrade two phones which is what i was looking for two different stores inconsistency. The store at pick and pay were almost closing and because my husband was enquiring about the phones and kept asking questions as would any customer wanting a new phone the ladies x2 were giggling and mumbling about asking alot of questions and they needing to leave... That put me off i felt akward and left. Visited the pavillion store but contract was not approved but service good compared to others... Not sure why not approved because few days later approved online.inconsistency again with mtn.. The lady said i could only upgrade to certain contacts but didnt provide much info about phones and the best part is i coukd not get the phone i wanted ao had to settle for s20 but not even in my colour of choice as it was not available. Delivery was post poned by me because i was hospitalized. Got my phone in jan as requested by me. Phone heating up. Called mtn as it was online and i waa still a little unwell expected it to be fetched but lady told me take all docs and packaging in store and they would give me options to exchange etc. Waited till my spouse could take me coz i couldn't walk without without getting tired. Got ti the chatsworth centre lady asked for invoice with delivery date else cant help. Dsv didnt provide that had to go back home call them and called mtn again as i could not manage to go back to a store as i was getting too tired. Called mtn again. Waited hours and stressed and only got help about two days later for device to be picked up which could have been done initially. Someone was going to tell me about out of box failure procedure but no one called back. Dsv fetched on jan 27th.no response by 4th feb i called. Again transferred to every dept till i was made aware i needed a ref ir tracking no. No one told me or neither did driver guve one which is his job. Called dsv got no. Mtn again onli to say device takes 10 days to get to where is needs and sales consultant will call back.i emailed her with no response and im currently holding on for help now with same redirection. Terrible service and stress to me. Worst part got a call from *** forgot the guys name as he said he will call me back and never did. He took my complaint made me think mtn could be okay again but it is a lie as he never followed up and gave me feedback... This is half of what i went through telephonically sad during this time
