Nobody wantsto take ownership of my query

I initially logged my query on 02/02/16. I have been through various touch points, calling your Contact Centre, emailing Customer Care, posting on Hello Peter, messaging on Facebook, visiting the Store - Coastlands Umhlanga - no resolution, just been bounced around. I have now logged this with Consumer Watch as I am at wits end. Please contact your store consultant for my latest correspondence and refer to mails and feedback on ***. I am on a 2GB plan with 2GB night express. Since Jan 16 I have been allocated 4GB in total and not the split. I used accordingly and believe I have been charged for 2GB, not my fault, I used what you allocated. In Feb16, I was again alloacted 4GB, but then 2GB was retracted, I was not replenished with 2GB night express. In Mar 16 I was only allocated 2GB, where is my 2GB night express that in signed up for? Please refund excess charges immediately and credit me with data I was entitled to OR refund me and cancel my contract, as you are messing up the deal I signed up for and I can't budget for these costs. You can't restructure the deal and raise subs whilst my contract is active. Understand my query in its entirety before responding feebly.
