Suspended mobile service

This account has never been in arrears: I have had problems on my contract (account number: Account number:1- ********** ********** ) from the 20 September 2017 starting with an online upgrade, not receiving the device. To get the online upgrade cancelled so that I can get the device in store took up and till 23 October 2017. The first time the account was suspended I thought it was because of the upgrade. First time dialled for a suspended account: 28 October, 30 October, 1 November, 16 November (in store and dialling call centre), 18 November, 25 November (in store and call centre), 27 November, 28 November, 29 November @ 06:56 again at 16:20, 30 November, 3 December, 4 December @ 06:37 and 15:37, 5 December. The contract is being suspended every evening between 9pm and 1 am in the morning. The account is not in arrears, it's not a network problem, also not a device problem, this is more than 5 weeks with still no resolution. I am paying over a R1000 per month for a service that I am not receiving. I keep on logging service requests that's being closed with no resolution, I am at the point where I phone the call centre twice a day. I want this upgrade cancelled. This is not only wasting my time to get the line activated every day but also interfering with the daily operations of running a business. I have now exceeded my call limit in dialling the call centre and the only means of contacting them is to go into a store where the consultant will again only log a service enquiry, absolutely useless processes.
