NO RESPONSE AS TO WHY I HAVENT RECEIVED DATA!!!

i took out a new contract about 2 months ago (I phone 6 as well). In my contract I get 100 minutes, r200 airtime and 500mb data. On 14 May (top up date) all I received was airtime & 25 smses. Where is my 500mb data? And my full minutes? After weeks of calling and calling I get no response forcing me to buy my own data! Yet I'm paying for it in my contract?!?! I logged a request at Bayside and to this date NO RESPONSE from anyone and Bayside says I must wait as your staff are striking! Well where is my money then!? Today (being a new month) I am still owed 500mb data for May. Now check this - I got credited today with 500mb & 100 minutes and 200 smses? What! I'm not paying for sms? Where does this even come from? And where is my airtime? You are messing my contract up and I'm paying for a ******** service. Rectify this immediately or I'm changing contracts for breach of contract and I will take this matter very. Far. I have all proof of updates and my logged requests that are being ignored! Make a plan, I want my money's worth. You are cheating me out of airtime and data!
