Worst customer service in the country

I've been approached by dstv price lock on the 13th of April request they phone me back the next day had to wait a week for someone to phone me. I requested their full package WITHOUT installation. On my application and when it was complete on the 20th the person who phoned me said the decoder should be delivered within 3 to 4 days so on day 3 I phoned them just to follow up on the process she said to me it will be delivered on Monday I was perfectly fine with that. On the Tuesday I followed up again just to hear that no parcel number has even been allocated to me and that an installer still has to be appointed to do my installation after I said no installation required I've requested numerous times that someone from the relevant department phones me to explain the issue. Eventually someone phones me to tell that they still have to appoint an installer yet again I told them there is no installation needed. I got another call on the 1st of May saying that my installation will happen on the 10th of May and still I have not requested that service from DSTV so by the time my decoder will be delivered it is going to be 21 days since approval and DSTV said to me that without installation 3-5 days and with installation 7-14 days yet here I am waiting for 21 days
