Poor service delivery

Good morning So today i have this issue with multichoice. There was a promotion going around where they give u a new explorer for free when you let them put you on a debit order for the montly installments and is said yes. However, on the day that the installer came he explained something totally different to me so i cancelled. The installer left with everything and nothing was installed in my house. I payed my dstv installment on 28th February 2022. Then on the 1st of march the debit order also went off for the R741.00. When this happened i went to the bank to reverse the order and also block them from taking any other debit orders in future as i cancelled the contract. So few days after this my dstv was cut and they sent a sms saying that they did not recieve my payment. I called the customer service and explained to the person what happened. The lady said she will re connect my dstv after the call the dstv was still off. The next day i phoned again. Explained the same thing all over again to someone else and the dstv was back on. 5days later the dstv was off again. Oh and they said that someone will call me back within 72hours. No one untill today has contacted me from dstv. I went to dstv n1 city and explained myself all over again. My dstv was back on again. Only to be off again 5days later. I called again same thing happened. I was put back on. I went back to dstv yesterday as my dstv was cut again. They put it back on again. Today when i woke up the dstv is off again. I am literally fed up with the poor service that i am getting from multichoice. Its taking time and wasting my money! I went twice to multichoice and i phoned more than 5 times and wait long for them to answer and they still put me on hold. O have almost spent alot of airtime and wasted my minutes. And its almost time to pay the new installment for the new month. But i had interruption service for this month of march.
