Very Disappointed in Lack of Service

I am so annoyed and disappointed with the service from Afrihost, Honestly I should have stayed with Telkom. I App**** for the 85gb + 85gb Promo and Paid for it on the 15th of November. Their Courier guys got hold of me about 3 weeks after to deliver the modem telling me that they are at my house and nobody is there (After I gave instruction to phone me 30 mins before so I can be there, I was at Work). I eventually gave them My work address and asked them to deliver there and they said okay they will deliver tomorrow... They never pitched. The following day they were at my house again and I was like WHY?, apparently I had to arrange with Afrihost for the change and not with them... Frustratingly I did so and even after changing the address to My workplace they never pitched... I got 2 SMS's stating that they could not get Hold of me which is an absolute Lie. I once again phoned and spoke to someone telling them I'm going on Holiday soon and need it this week (Was the week of the 18 - 22 December) He told me that he escalated the matter and they will deliver within that week... They Never came or notified me anything... I got an SMS stating that the package was cancelled due to unavailability... I left it there and disappointedly went on Holiday. Coming back from Holiday I had to phone Numerous times again to get this Modem delivered and eventually It was Delivered on the 13th of January...

NOW

Apparently the package was cancelled and I only received 85gb and not the additional 85gb... After a heated discussion with Tido he assured me that I will be getting the extra 85gb and also sent me an email to reassure me. I was told not to insert the sim until I receive an SMS telling me that the additional data has been allocated which I haven't... It is now FOUR days later and still no SMS, I phoned Yesterday and spoke to someone and explained my whole situation again and he said he'll phone me Back... He never did. Today I phoned and asked to speak to Tido, (Since he's the one who assured me) and he was away for tea, The lady I spoke to assured me he'll phone me back and I told her you guys never phone back because I'm still waiting for the call yesterday and she said no She'll make sure... To no surprise, I have not been phoned back. I have wasted hundreds of rands worth of airtime and still i'm on square one.

I paid for the month already and heading close to end of the month and I still have not used any data, This is really unacceptable and I'm on the point of returning this modem and asking for a refund for both modem and monthly bill, What is going on, Why is it so difficult getting any service from you guys.

Please escalate this, I'm really frustrated now.
