Not receiving the servic what is agreed in contrac

This is my my 4th complaint of bad service. I am/use to be a loyal Telkom customer never experienced any bad service in my first cellphone contract. However the problems piled up with my second one. <br> Firstly my contract was taken out but never really activated. Secondly my Telkom wifi data was never added to the account. (ISSUE WAS RESOLVED AFTER MONTHS OF STRUGGLING).<br> Thirdly my Telkom mobile to Telkom mobile calls weren't free as stated (THIS ISSUE WAS ALSO RESOLVED AFTER A LENGTHY STRUGGLE ). I was then foned and advised that I will receive a R275 refund for all the calls I made to these numbers however I have never received it.<br> Then lastly my new struggle my reoccurring all network 1 gig of Telkom data was never added to my account on the 1st. I foned a contact centre agent who told me I have used it in a few hours after a few words she realised that when she looked at my data usage I didn't use it. Then I went into the store to check it out and they realised it was never allocated.<br> I am tired of this constant struggle, I cannot go on like this please help me. I don't feel like you guys are providin me with what we agreed upon in contract and to what I am paying every month
