Worst service ever

I have never received such a terrible service in my life. The problem started when I took a contract with them. I also took out insurance for the device (laptop) and was billed from the first month for the insurance and was told that the insurance contract was going to be forwarded to me. When I did not receive the contract, as promised, I called them and they told me that my laptop was not insured, even though I never defaulted in paying the insurance premium. I made numerous calls, trying to sort out the problem and there was no co-operation from them. As a result, it took me two months to get the problem solved and I finally got the contract at the end of February. I was not happy with the contract and I decided to cancel it. I was supposed to pay my last premium for the insurance at the end of April, but I was billed again at the end of May and June. As I am writing this, I am still waiting for the refund which I lodged a claim for at the beginning af June (that was before I was billed again at the end of June). Mtn is pathetic.
