MTN billing issue a ****

I Have a contracts with MTN , my bill is R1300 for 2 contracts which both where due for Upgrade . 19 October I upgraded contract number 1, on the 21st I upgraded contract number 2 . Contract number 2 got approved and benefits loaded a day later .

Followed up with MTN which they gave me numbers for Mdondo their online sales 3rd party team . I followed every other day with mondo and I have reference numbers . MTN twitter support said they will escalate the matter and we are on our fourth week. 3rd week I was told the contract failed to upgrade and no one advised me . My bill for Nov ‘23 was supposed to be R300 for both numbers for only data packages of 15 gigs each. Who is responsible for the other R1000 . I have been following up for 3 weeks and their service team leads no one managed to sort this it my issue.

Lots of escalations from twitter and mondo nothing . Who is liable for that bill . They can’t keep me in a package I don’t want .
