contract cancellation ran arounds 6 day contract cant connect

I have been to your store three in this 8 days due to the inability to connect to the internet while the network is showing as connected The slowness that one device is reporting causes a lot of fustrations within my household The second query which we had was how the data was transferred into the sim I was told we would have prorata data for the 2 days 28-30 then after 20 gigs transferred for anytime And by Saturday when we went to the centurion store only 8.83 gigs was showing as the Data and the sales consultant could not explain that to us . After the store technician or one of their technical guys took the device and did changes we still experienced the same problem of not being able to connect to the internet .on Monday the 4th I called the customer line and was transferred to the retentions dept who referred back to the store I did that we spent 2 hours while the technician tried his best to resolve my problem eventually he made me fill a form to cancel the contract .yesterday I made follow up with the call centre and the retentions dept zanele told me they don't handle those cancellations but their channels dept I eventually called the store back n was told the query will be escalated to their supervisor .I called mtn this morning and was told the channels dept only takes instructions from the store

if this is the type of running around I have to do in 7 days and still not have the response of this contract being cancelled how then will my 24 months be I request confirmation that this contract is cancelled as its still within the CPA window when I cancelled I don't expect to be charged any penalties I am willing to pay for the data used thus far . ********** 082 data line .
